Syntax :

map(fun, iter)

Parameters :

fun : It is a function to which map passes each element of given iterable.
iter : It is a iterable which is to be mapped.

NOTE : You can pass one or more iterable to the map() function.

Returns :

Returns a list of the results after applying the given function  
to each item of a given iterable (list, tuple etc.)

NOTE : The returned value from map() (map object) then can be passed to functions like list() (to create a list), set() (to create a set) .

Apa fungsi map pada Python?

map() adalah salah satu built-in function di Python yang dapat digunakan untuk menerapkan sebuah fungsi pada semua elemen dari objek yang bertipe iterable seperti list, tuple, dan sebagainya. Hasil dari map() adalah berupa objek map yang dapat dikonversi kembali menjadi objek list, tuple, dan lainnya.

Apa yang dimaksud dengan Python Maps?

Python Map () adalah metode terintegrasi yang memungkinkan semua objek diinterpretasikan dan diterjemahkan ke dalam iterable, bukan loop eksplisit, biasanya disebut sebagai mapping.

Apa fungsi append pada Python?

Append. Salah satu fitur dalam array python yang cukup sering digunakan adalah fungsi append. Fungsi append ini berguna untuk menambahkan nilai array pada urutan terakhir. Fungsi ini sedikit berbeda dengan fungsi insert, dimana fungsi insert bisa menambahkan nilai array pada posisi tertentu.

Apa yang dimaksud dengan list di Python?

List adalah tipe data yang paling serbaguna dalam bahasa pemrograman Python. List ditulis sebagai daftar nilai yang dipisahkan koma (item) antara tanda kurung siku. Dalam membuat list pada Python sangatlah sederhana. Tinggal memasukkan berbagai nilai yang dipisahkan dengan tanda koma di antara tanda kurung siku.
