Metode date.fromtimestamp(~) Python mengonversi stempel waktu Unix menjadi objek date

Show

Stempel waktu Unix adalah jumlah detik antara tanggal tertentu dan 1 Januari 1970 UTC

1. timestamp . Unix timestamp

The Unix timestamp to convert to corresponding date object

A date object based off the provided Unix timestamp

While date and time arithmetic is supported, the focus of the implementation is on efficient attribute extraction for output formatting and manipulation

Aware and Naive Objects

Date and time objects may be categorized as “aware” or “naive” depending on whether or not they include timezone information

With sufficient knowledge of applicable algorithmic and political time adjustments, such as time zone and daylight saving time information, an aware object can locate itself relative to other aware objects. An aware object represents a specific moment in time that is not open to interpretation.

A naive object does not contain enough information to unambiguously locate itself relative to other date/time objects. Whether a naive object represents Coordinated Universal Time (UTC), local time, or time in some other timezone is purely up to the program, just like it is up to the program whether a particular number represents metres, miles, or mass. Naive objects are easy to understand and to work with, at the cost of ignoring some aspects of reality

For applications requiring aware objects, and objects have an optional time zone information attribute, 

>>> delta2 > delta1
True
>>> delta2 > 5
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: '>' not supported between instances of 'datetime.timedelta' and 'int'
4, that can be set to an instance of a subclass of the abstract class. These objects capture information about the offset from UTC time, the time zone name, and whether daylight saving time is in effect

Only one concrete class, the class, is supplied by the module. The class can represent simple timezones with fixed offsets from UTC, such as UTC itself or North American EST and EDT timezones. Supporting timezones at deeper levels of detail is up to the application. The rules for time adjustment across the world are more political than rational, change frequently, and there is no standard suitable for every application aside from UTC

Constants

The module exports the following constants

datetime. MINYEAR

The smallest year number allowed in a or object. is 

>>> # Components of another_year add up to exactly 365 days
>>> from datetime import timedelta
>>> year = timedelta(days=365)
>>> another_year = timedelta(weeks=40, days=84, hours=23,
..                          minutes=50, seconds=600)
>>> year == another_year
True
>>> year.total_seconds()
31536000.0
5

datetime. MAXYEAR

The largest year number allowed in a or object. is 

>>> # Components of another_year add up to exactly 365 days
>>> from datetime import timedelta
>>> year = timedelta(days=365)
>>> another_year = timedelta(weeks=40, days=84, hours=23,
..                          minutes=50, seconds=600)
>>> year == another_year

Common Properties

The , , , and types share these common features

  • Objects of these types are immutable

  • Objects of these types are hashable, meaning that they can be used as dictionary keys

  • Objects of these types support efficient pickling via the module

Determining if an Object is Aware or Naive

Objects of the type are always naive

An object of type or may be aware or naive

A object d is aware if both of the following hold

  1. >>> from datetime import timedelta
>>> delta = timedelta(
..     days=50,
..     seconds=27,

.. )
>>> # Only days, seconds, and microseconds remain

datetime.timedelta(days=64, seconds=29156, microseconds=10)
    03

  2. >>> from datetime import timedelta

>>> # Only days, seconds, and microseconds remain
>>> delta
datetime.timedelta(days=64, seconds=29156, microseconds=10)
    03

Otherwise, d is naive

A object t is aware if both of the following hold

  1. >>> from datetime import timedelta
>>> delta = timedelta(
..     days=50,
..     seconds=27,
..     microseconds=10,

.. )
>>> # Only days, seconds, and microseconds remain

datetime.timedelta(days=64, seconds=29156, microseconds=10)
    03

  2. >>> from datetime import timedelta
>>> delta = timedelta(
..     days=50,

datetime.timedelta(days=64, seconds=29156, microseconds=10)
    09 does not return 
    >>> from datetime import timedelta

..     weeks=2
.. )
>>> # Only days, seconds, and microseconds remain
>>> delta
datetime.timedelta(days=64, seconds=29156, microseconds=10)
    03

Otherwise, t is naive

The distinction between aware and naive doesn’t apply to objects

Objects

A object represents a duration, the difference between two dates or times

class datetime. timedelta(days=0 , seconds=0 , microseconds=0 , milliseconds=0 , minutes=0 , hours=0 , weeks=0)

All arguments are optional and default to 

>>> from datetime import timedelta
>>> delta = timedelta(
..     days=50,
..     seconds=27,
..     microseconds=10,
..     milliseconds=29000,
..     minutes=5,
..     hours=8,
..     weeks=2
.. )
>>> # Only days, seconds, and microseconds remain
>>> delta
datetime.timedelta(days=64, seconds=29156, microseconds=10)
14. Arguments may be integers or floats, and may be positive or negative

Only days, seconds and microseconds are stored internally. Arguments are converted to those units

  • A millisecond is converted to 1000 microseconds

  • A minute is converted to 60 seconds

  • An hour is converted to 3600 seconds

  • A week is converted to 7 days

and days, seconds and microseconds are then normalized so that the representation is unique, with

  • >>> from datetime import timedelta
>>> delta = timedelta(
..     days=50,
..     seconds=27,
..     microseconds=10,
..     milliseconds=29000,
..     minutes=5,
..     hours=8,
..     weeks=2
.. )
>>> # Only days, seconds, and microseconds remain
>>> delta
datetime.timedelta(days=64, seconds=29156, microseconds=10)
    15

  • >>> from datetime import timedelta
>>> delta = timedelta(
..     days=50,
..     seconds=27,
..     microseconds=10,
..     milliseconds=29000,
..     minutes=5,
..     hours=8,
..     weeks=2
.. )
>>> # Only days, seconds, and microseconds remain
>>> delta
datetime.timedelta(days=64, seconds=29156, microseconds=10)
    16 (the number of seconds in one day)

  • >>> from datetime import timedelta
>>> delta = timedelta(
..     days=50,
..     seconds=27,
..     microseconds=10,
..     milliseconds=29000,
..     minutes=5,
..     hours=8,
..     weeks=2
.. )
>>> # Only days, seconds, and microseconds remain
>>> delta
datetime.timedelta(days=64, seconds=29156, microseconds=10)
    _17

The following example illustrates how any arguments besides days, seconds and microseconds are “merged” and normalized into those three resulting attributes

>>> from datetime import timedelta
>>> delta = timedelta(
..     days=50,
..     seconds=27,
..     microseconds=10,
..     milliseconds=29000,
..     minutes=5,
..     hours=8,
..     weeks=2
.. )
>>> # Only days, seconds, and microseconds remain
>>> delta
datetime.timedelta(days=64, seconds=29156, microseconds=10)

If any argument is a float and there are fractional microseconds, the fractional microseconds left over from all arguments are combined and their sum is rounded to the nearest microsecond using round-half-to-even tiebreaker. If no argument is a float, the conversion and normalization processes are exact (no information is lost)

If the normalized value of days lies outside the indicated range, is raised

Note that normalization of negative values may be surprising at first. For example

>>> from datetime import timedelta
>>> d = timedelta(microseconds=-1)
>>> (d.days, d.seconds, d.microseconds)
(-1, 86399, 999999)

Kalender ISO adalah varian kalender Gregorian yang banyak digunakan.

Tahun ISO terdiri dari 52 atau 53 minggu penuh, dan satu minggu dimulai pada hari Senin dan berakhir pada hari Minggu. Minggu pertama tahun ISO adalah minggu kalender pertama (Gregorian) dalam setahun yang berisi hari Kamis. Ini disebut minggu nomor 1, dan tahun ISO pada hari Kamis itu sama dengan tahun Gregoriannya

Misalnya tahun 2004 dimulai pada hari Kamis, maka minggu pertama ISO tahun 2004 dimulai pada hari Senin, 29 Des 2003 dan berakhir pada hari Minggu, 4 Jan 2004

Compares to . (4)

  1. datetime2 is a duration of timedelta removed from datetime1, moving forward in time if 

    >>> from datetime import timedelta
>>> d = timedelta(microseconds=-1)
>>> (d.days, d.seconds, d.microseconds)
(-1, 86399, 999999)
    21 > 0, or backward if 
    >>> from datetime import timedelta
>>> d = timedelta(microseconds=-1)
>>> (d.days, d.seconds, d.microseconds)
(-1, 86399, 999999)
    21 < 0. The result has the same attribute as the input datetime, and datetime2 - datetime1 == timedelta after. is raised if datetime2. year would be smaller than or larger than . Note that no time zone adjustments are done even if the input is an aware object

  2. Computes the datetime2 such that datetime2 + timedelta == datetime1. As for addition, the result has the same attribute as the input datetime, and no time zone adjustments are done even if the input is aware

  3. Subtraction of a from a is defined only if both operands are naive, or if both are aware. If one is aware and the other is naive, is raised

    If both are naive, or both are aware and have the same attribute, the attributes are ignored, and the result is a object t such that 

    >>> from datetime import timedelta
>>> delta1 = timedelta(seconds=57)
>>> delta2 = timedelta(hours=25, seconds=2)
>>> delta2 != delta1
True
>>> delta2 == 5
False
    22. No time zone adjustments are done in this case

    If both are aware and have different attributes, 

    >>> from datetime import timedelta
>>> delta1 = timedelta(seconds=57)
>>> delta2 = timedelta(hours=25, seconds=2)
>>> delta2 != delta1
True
>>> delta2 == 5
False
    24 acts as if a and b were first converted to naive UTC datetimes first. The result is 
    >>> from datetime import timedelta
>>> delta1 = timedelta(seconds=57)
>>> delta2 = timedelta(hours=25, seconds=2)
>>> delta2 != delta1
True
>>> delta2 == 5
False
    25 except that the implementation never overflows

  4. datetime1 is considered less than datetime2 when datetime1 precedes datetime2 in time

    If one comparand is naive and the other is aware, is raised if an order comparison is attempted. For equality comparisons, naive instances are never equal to aware instances

    If both comparands are aware, and have the same attribute, the common attribute is ignored and the base datetimes are compared. If both comparands are aware and have different attributes, the comparands are first adjusted by subtracting their UTC offsets (obtained from 

    >>> from datetime import timedelta
>>> delta1 = timedelta(seconds=57)
>>> delta2 = timedelta(hours=25, seconds=2)
>>> delta2 != delta1
True
>>> delta2 == 5
False
    30)

    Changed in version 3. 3. Equality comparisons between aware and naive instances don’t raise .

    Note

    In order to stop comparison from falling back to the default scheme of comparing object addresses, datetime comparison normally raises if the other comparand isn’t also a object. However, 

    >>> from datetime import timedelta
>>> d = timedelta(microseconds=-1)
>>> (d.days, d.seconds, d.microseconds)
(-1, 86399, 999999)
    41 is returned instead if the other comparand has a 
    >>> from datetime import timedelta
>>> d = timedelta(microseconds=-1)
>>> (d.days, d.seconds, d.microseconds)
(-1, 86399, 999999)
    42 attribute. This hook gives other kinds of date objects a chance at implementing mixed-type comparison. If not, when a object is compared to an object of a different type, is raised unless the comparison is 
    >>> from datetime import timedelta
>>> delta = timedelta(
..     days=50,
..     seconds=27,
..     microseconds=10,
..     milliseconds=29000,

datetime. astimezone(tz=None)

Return a object with new attribute tz, adjusting the date and time data so the result is the same UTC time as self, but in tz’s local time

If provided, tz must be an instance of a subclass, and its and methods must not return

>>> from datetime import timedelta
>>> delta1 = timedelta(seconds=57)
>>> delta2 = timedelta(hours=25, seconds=2)
>>> delta2 != delta1

>>> delta2 == 5
False
67

If you merely want to attach a time zone object tz to a datetime dt without adjustment of date and time data, use 

>>> from datetime import timedelta
>>> delta1 = timedelta(seconds=57)
>>> delta2 = timedelta(hours=25, seconds=2)
>>> delta2 != delta1
True
>>> delta2 == 5
False
68. If you merely want to remove the time zone object from an aware datetime dt without conversion of date and time data, use 
>>> from datetime import timedelta
>>> delta1 = timedelta(seconds=57)
>>> delta2 = timedelta(hours=25, seconds=2)
>>> delta2 != delta1
True
>>> delta2 == 5
False
69

Note that the default method can be overridden in a subclass to affect the result returned by . Ignoring error cases, acts like

>>> from datetime import timedelta
>>> d = timedelta(microseconds=-1)
>>> (d.days, d.seconds, d.microseconds)
(-1, 86399, 999999)

..     hours=8,
..     weeks=2
.. )
>>> # Only days, seconds, and microseconds remain
>>> delta
datetime.timedelta(days=64, seconds=29156, microseconds=10)
03, or an instance of a subclass. The remaining arguments must be integers in the following ranges

  • >>> from datetime import timedelta
>>> d = timedelta(microseconds=-1)
>>> (d.days, d.seconds, d.microseconds)
(-1, 86399, 999999)

(A repeated interval occurs when clocks are rolled back at the end of daylight saving time or when the UTC offset for the current zone is decreased for political reasons. ) The value 0 (1) represents the earlier (later) of the two moments with the same wall time representation

New in version 3. 6

objects support comparison of to , where a is considered less than b when a precedes b in time. If one comparand is naive and the other is aware, is raised if an order comparison is attempted. For equality comparisons, naive instances are never equal to aware instances

If both comparands are aware, and have the same attribute, the common attribute is ignored and the base times are compared. If both comparands are aware and have different attributes, the comparands are first adjusted by subtracting their UTC offsets (obtained from 

>>> from datetime import timedelta
>>> delta1 = timedelta(seconds=57)
>>> delta2 = timedelta(hours=25, seconds=2)
>>> delta2 != delta1
True
>>> delta2 == 5
False
30). In order to stop mixed-type comparisons from falling back to the default comparison by object address, when a object is compared to an object of a different type, is raised unless the comparison is 
>>> from datetime import timedelta
>>> delta = timedelta(

.. )
>>> # Only days, seconds, and microseconds remain
>>> delta
datetime.timedelta(days=64, seconds=29156, microseconds=10)
76. The latter cases return or , respectively

Changed in version 3. 3. Equality comparisons between aware and naive instances don’t raise .

In Boolean contexts, a object is always considered to be true

Changed in version 3. 5. Before Python 3. 5, a object was considered to be false if it represented midnight in UTC. This behavior was considered obscure and error-prone and has been removed in Python 3. 5. See bpo-13936 for full details.

Other constructor

classmethod time. fromisoformat(time_string)

Return a corresponding to a time_string in any valid ISO 8601 format, with the following exceptions

  3. Fractional seconds may have any number of digits (anything beyond 6 will be truncated)

  4. Fractional hours and minutes are not supported

Objects

kelas tanggal waktu. tzinfo

This is an abstract base class, meaning that this class should not be instantiated directly. Define a subclass of to capture information about a particular time zone

Instance dari (subclass konkret dari) dapat diteruskan ke konstruktor untuk dan objek. Objek yang terakhir melihat atributnya sebagai waktu lokal, dan objek mendukung metode yang mengungkapkan offset waktu lokal dari UTC, nama zona waktu, dan offset DST, semuanya terkait dengan objek tanggal atau waktu yang diteruskan ke mereka

Anda perlu menurunkan subkelas konkret, dan (setidaknya) menyediakan implementasi dari metode standar yang dibutuhkan oleh metode yang Anda gunakan. The module provides , a simple concrete subclass of which can represent timezones with fixed offset from UTC such as UTC itself or North American EST and EDT

Special requirement for pickling. Subkelas harus memiliki metode 

>>> from datetime import timedelta

datetime.timedelta(days=3285)
>>> three_years = nine_years // 3
>>> three_years, three_years.days // 365
(datetime.timedelta(days=1095), 3)
_18 yang dapat dipanggil tanpa argumen, selain itu dapat diasamkan tetapi mungkin tidak diurai lagi. Ini adalah persyaratan teknis yang mungkin dilonggarkan di masa mendatang

Subkelas konkret mungkin perlu mengimplementasikan metode berikut. Exactly which methods are needed depends on the uses made of aware objects. If in doubt, simply implement all of them

tzinfo. utcoffset(dt)

Kembalikan offset waktu lokal dari UTC, sebagai objek yang positif di sebelah timur UTC. Jika waktu lokal di sebelah barat UTC, ini harus negatif

Ini mewakili total offset dari UTC; . Jika offset UTC tidak diketahui, kembalikan

_83 jika DST tidak berlaku. If DST is in effect, return the offset as a object (see for details). Perhatikan bahwa offset DST, jika berlaku, telah ditambahkan ke offset UTC yang dikembalikan oleh , jadi tidak perlu berkonsultasi kecuali jika Anda tertarik untuk mendapatkan info DST secara terpisah. Misalnya, panggil metode atributnya untuk menentukan bagaimana bendera

Implementasi standar kenaikan gaji

These methods are called by a or object, in response to their methods of the same names. A object passes itself as the argument, and a object passes

_78 untuk mengembalikan offset standar UTC, karena tidak ada konvensi lain untuk menemukan offset standar

When a object is passed in response to a method,

>>> ten_years = 10 * year
>>> ten_years
datetime.timedelta(days=3650)
>>> ten_years.days // 365

>>> nine_years = ten_years - year
>>> nine_years
datetime.timedelta(days=3285)
>>> three_years = nine_years // 3
>>> three_years, three_years.days // 365
(datetime.timedelta(days=1095), 3)
81 is the same object as self. metode dapat mengandalkan ini, kecuali kode pengguna memanggil metode secara langsung. The intent is that the methods interpret dt as being in local time, and not need worry about objects in other timezones

There is one more method that a subclass may wish to override

tzinfo. fromutc(dt)

Ini dipanggil dari implementasi default. Ketika dipanggil dari situ, 

>>> from datetime import timedelta
>>> year = timedelta(days=365)
>>> ten_years = 10 * year
>>> ten_years
datetime.timedelta(days=3650)
>>> ten_years.days // 365
10
>>> nine_years = ten_years - year
>>> nine_years
datetime.timedelta(days=3285)
>>> three_years = nine_years // 3
>>> three_years, three_years.days // 365
(datetime.timedelta(days=1095), 3)
81 adalah self, dan data tanggal dan waktu dt harus dilihat sebagai menyatakan waktu UTC. Tujuannya adalah untuk menyesuaikan data tanggal dan waktu, mengembalikan waktu yang setara dalam waktu lokal sendiri

Sebagian besar subclass harus dapat mewarisi implementasi default tanpa masalah. Ini cukup kuat untuk menangani zona waktu fixed-offset, dan zona waktu memperhitungkan waktu standar dan siang hari, dan yang terakhir bahkan jika waktu transisi DST berbeda di tahun yang berbeda. Contoh zona waktu yang implementasi defaultnya mungkin tidak ditangani dengan benar dalam semua kasus adalah di mana offset standar (dari UTC) bergantung pada tanggal dan waktu tertentu yang berlalu, yang dapat terjadi karena alasan politik. Implementasi default dari 

>>> from datetime import timedelta
>>> delta1 = timedelta(seconds=57)
>>> delta2 = timedelta(hours=25, seconds=2)
>>> delta2 != delta1
True
>>> delta2 == 5
False
_72 dan mungkin tidak menghasilkan hasil yang Anda inginkan jika hasilnya adalah salah satu jam yang mengangkang saat offset standar berubah

Melewatkan kode untuk kasus kesalahan, seperti implementasi default

>>> from datetime import timedelta
>>> delta1 = timedelta(seconds=57)
>>> delta2 = timedelta(hours=25, seconds=2)
>>> delta2 != delta1
True
>>> delta2 == 5

>>> ten_years = 10 * year
>>> ten_years

>>> nine_years = ten_years - year
>>> nine_years
datetime.timedelta(days=3285)
>>> three_years = nine_years // 3
>>> three_years, three_years.days // 365
(datetime.timedelta(days=1095), 3)
_95 berikut ada beberapa contoh kelas

>>> from datetime import timedelta
>>> delta1 = timedelta(seconds=57)
>>> delta2 = timedelta(hours=25, seconds=2)
>>> delta2 != delta1
True
>>> delta2 == 5
False
_2

Note that there are unavoidable subtleties twice per year in a subclass accounting for both standard and daylight time, at the DST transition points. Untuk konkretnya, pertimbangkan US Eastern (UTC -0500), di mana EDT dimulai menit setelah 1. 59 (EST) pada hari Minggu kedua bulan Maret, dan berakhir menit setelah 1. 59 (EDT) on the first Sunday in November

>>> from datetime import timedelta
>>> delta1 = timedelta(seconds=57)
>>> delta2 = timedelta(hours=25, seconds=2)
>>> delta2 != delta1
True
>>> delta2 == 5
False
_3

Saat DST dimulai (baris "mulai"), jam dinding lokal melompat dari 1. 59 sampai 3. 00. Waktu dinding dalam bentuk 2. MM tidak masuk akal pada hari itu, jadi 

>>> from datetime import timedelta
>>> year = timedelta(days=365)
>>> ten_years = 10 * year
>>> ten_years
datetime.timedelta(days=3650)
>>> ten_years.days // 365
10
>>> nine_years = ten_years - year
>>> nine_years
datetime.timedelta(days=3285)
>>> three_years = nine_years // 3
>>> three_years, three_years.days // 365
(datetime.timedelta(days=1095), 3)
98 tidak akan memberikan hasil dengan 
>>> from datetime import timedelta
>>> year = timedelta(days=365)
>>> ten_years = 10 * year
>>> ten_years
datetime.timedelta(days=3650)
>>> ten_years.days // 365
10
>>> nine_years = ten_years - year
>>> nine_years
datetime.timedelta(days=3285)
>>> three_years = nine_years // 3
>>> three_years, three_years.days // 365
(datetime.timedelta(days=1095), 3)
99 pada hari DST dimulai. Misalnya, pada transisi maju musim semi tahun 2016, kita dapatkan

>>> from datetime import timedelta
>>> delta1 = timedelta(seconds=57)
>>> delta2 = timedelta(hours=25, seconds=2)
>>> delta2 != delta1
True
>>> delta2 == 5
False
_4

Saat DST berakhir ("garis akhir"), ada potensi masalah yang lebih buruk. there’s an hour that can’t be spelled unambiguously in local wall time. jam terakhir siang hari. In Eastern, that’s times of the form 5. MM UTC on the day daylight time ends. Jam dinding lokal melompat dari 1. 59 (waktu siang hari) kembali ke 1. 00 (waktu standar) lagi. Local times of the form 1. MM ambigu.

72 mimics the local clock’s behavior by mapping two adjacent UTC hours into the same local hour then. In the Eastern example, UTC times of the form 5. MM and 6. MM keduanya dipetakan ke 1. MM saat dikonversi ke Timur, tetapi waktu sebelumnya memiliki atribut yang disetel ke 0 dan waktu selanjutnya disetel ke 1. Misalnya, pada transisi musim gugur tahun 2016, kami mendapatkan

>>> from datetime import timedelta
>>> delta1 = timedelta(seconds=57)
>>> delta2 = timedelta(hours=25, seconds=2)
>>> delta2 != delta1
True
>>> delta2 == 5
False
_5

Perhatikan bahwa instance yang berbeda hanya dengan nilai atribut dianggap sama dalam perbandingan

Aplikasi yang tidak tahan dengan ambiguitas dinding-waktu harus secara eksplisit memeriksa nilai atribut atau menghindari penggunaan subkelas hibrid;

1 membawa basis data zona waktu IANA (juga dikenal sebagai basis data Olson) ke Python, dan penggunaannya disarankan

Basis data zona waktu IANA

Basis Data Zona Waktu (sering disebut tz, tzdata, atau zoneinfo) berisi kode dan data yang mewakili riwayat waktu setempat untuk banyak lokasi representatif di seluruh dunia. Ini diperbarui secara berkala untuk mencerminkan perubahan yang dibuat oleh badan politik terhadap batas zona waktu, offset UTC, dan aturan penghematan waktu siang hari

Objects

Kelas tersebut adalah subkelas dari , setiap turunannya mewakili zona waktu yang ditentukan oleh offset tetap dari UTC

Objek dari kelas ini tidak dapat digunakan untuk merepresentasikan informasi zona waktu di lokasi di mana offset yang berbeda digunakan pada hari yang berbeda dalam setahun atau di mana perubahan historis telah dibuat ke waktu sipil

kelas tanggal waktu. zona waktu(offset , nama=None)

The offset argument must be specified as a object representing the difference between the local time and UTC. Itu harus benar-benar antara 

>>> from datetime import timedelta
>>> year = timedelta(days=365)
>>> ten_years = 10 * year
>>> ten_years
datetime.timedelta(days=3650)
>>> ten_years.days // 365
10
>>> nine_years = ten_years - year
>>> nine_years
datetime.timedelta(days=3285)
>>> three_years = nine_years // 3
>>> three_years, three_years.days // 365
(datetime.timedelta(days=1095), 3)
26 dan 
>>> from datetime import timedelta
>>> year = timedelta(days=365)
>>> ten_years = 10 * year
>>> ten_years
datetime.timedelta(days=3650)

Argumen nama bersifat opsional. Jika ditentukan, itu harus berupa string yang akan digunakan sebagai nilai yang dikembalikan oleh metode

Baru di versi 3. 2

Changed in version 3. 7. The UTC offset is not restricted to a whole number of minutes.

zona waktu. utcoffset(dt)

Detil Teknis

Secara umum, 

>>> from datetime import date
>>> date.fromisoformat('2019-12-04')
datetime.date(2019, 12, 4)
>>> date.fromisoformat('20191204')
datetime.date(2019, 12, 4)
>>> date.fromisoformat('2021-W01-1')
datetime.date(2021, 1, 4)
98 bertindak seperti 
>>> from datetime import date
>>> d = date(2002, 12, 31)
>>> d.replace(day=26)
datetime.date(2002, 12, 26)
00 modul meskipun tidak semua objek mendukung metode 
>>> from datetime import timedelta
>>> d = timedelta(microseconds=-1)
>>> (d.days, d.seconds, d.microseconds)
(-1, 86399, 999999)
42

Untuk metode kelas, nilai defaultnya adalah 

>>> from datetime import date
>>> d = date(2002, 12, 31)
>>> d.replace(day=26)
datetime.date(2002, 12, 26)
03. setiap komponen yang tidak ditentukan dalam string format akan ditarik dari nilai default.

Menggunakan 

>>> from datetime import date
>>> d = date(2002, 12, 31)
>>> d.replace(day=26)
datetime.date(2002, 12, 26)
_04 sama dengan

>>> from datetime import timedelta
>>> d = timedelta(microseconds=-1)
>>> (d.days, d.seconds, d.microseconds)
(-1, 86399, 999999)
1

kecuali jika format menyertakan komponen sub-detik atau informasi offset zona waktu, yang didukung di 

>>> from datetime import date
>>> d = date(2002, 12, 31)
>>> d.replace(day=26)
datetime.date(2002, 12, 26)
05 tetapi dibuang oleh 
>>> from datetime import date
>>> d = date(2002, 12, 31)
>>> d.replace(day=26)
datetime.date(2002, 12, 26)
06

Untuk objek, kode format tahun, bulan, dan hari tidak boleh digunakan, karena objek tidak memiliki nilai seperti itu. Jika tetap digunakan, 

>>> from datetime import date
>>> d = date(2002, 12, 31)
>>> d.replace(day=26)
datetime.date(2002, 12, 26)
09 diganti untuk tahun, dan 
>>> # Components of another_year add up to exactly 365 days
>>> from datetime import timedelta
>>> year = timedelta(days=365)
>>> another_year = timedelta(weeks=40, days=84, hours=23,
..                          minutes=50, seconds=600)
>>> year == another_year
True
>>> year.total_seconds()
31536000.0
5 untuk bulan dan hari

Untuk objek, kode format jam, menit, detik, dan mikrodetik tidak boleh digunakan, karena objek tidak memiliki nilai seperti itu. Jika mereka tetap digunakan, 

>>> from datetime import timedelta
>>> delta = timedelta(
..     days=50,
..     seconds=27,
..     microseconds=10,
..     milliseconds=29000,
..     minutes=5,
..     hours=8,
..     weeks=2
.. )
>>> # Only days, seconds, and microseconds remain
>>> delta
datetime.timedelta(days=64, seconds=29156, microseconds=10)
_14 diganti untuk mereka

Untuk alasan yang sama, penanganan string format yang berisi poin kode Unicode yang tidak dapat direpresentasikan dalam rangkaian karakter lokal saat ini juga bergantung pada platform. Pada beberapa platform, titik kode seperti itu dipertahankan utuh dalam keluaran, sementara pada platform lain 

>>> from datetime import date
>>> date.fromisoformat('2019-12-04')
datetime.date(2019, 12, 4)
>>> date.fromisoformat('20191204')
datetime.date(2019, 12, 4)
>>> date.fromisoformat('2021-W01-1')
datetime.date(2021, 1, 4)
50 dapat menaikkan atau mengembalikan string kosong sebagai gantinya

Catatan

  1. Karena formatnya bergantung pada lokal saat ini, kehati-hatian harus dilakukan saat membuat asumsi tentang nilai keluaran. Pengurutan bidang akan bervariasi (misalnya, "bulan/hari/tahun" versus "hari/bulan/tahun"), dan hasilnya mungkin berisi karakter Unicode yang dikodekan menggunakan penyandian default lokal (misalnya, jika lokal saat ini adalah 

    >>> from datetime import date
>>> d = date(2002, 12, 31)
>>> d.replace(day=26)
datetime.date(2002, 12, 26)
    16,

  2. Metode

datetime.date(2019, 12, 4)
>>> date.fromisoformat('2021-W01-1')
datetime.date(2021, 1, 4)
    _41 dapat menguraikan tahun dalam rentang [1, 9999] penuh, tetapi tahun <1000 harus diisi nol hingga lebar 4 digit

    Berubah di versi 3. 2. Dalam versi sebelumnya, metode 

    >>> from datetime import date

datetime.date(2019, 12, 4)
>>> date.fromisoformat('2021-W01-1')
datetime.date(2021, 1, 4)
    40 dibatasi hingga tahun >= 1900.

    Berubah di versi 3. 3. Dalam versi 3. 2, 

    >>> from datetime import date

datetime.date(2019, 12, 4)
>>> date.fromisoformat('2021-W01-1')
datetime.date(2021, 1, 4)
    72 hanya memengaruhi bidang output jam jika direktif 
    >>> from datetime import date

datetime.date(2019, 12, 4)
>>> date.fromisoformat('20191204')
datetime.date(2019, 12, 4)
>>> date.fromisoformat('2021-W01-1')
datetime.date(2021, 1, 4)
    71 digunakan untuk mengurai jam

  4. Berbeda dengan modul, modul tidak mendukung detik kabisat

  5. Saat digunakan dengan metode 

    >>> from datetime import date
