Creating bytes objects in PythonStrings represent text (human language that is). For example, here we have a string named But there's another type that's closely associated with strings, which kind of looks like making a string with a That
Strings represent text, bytes objects represent binary dataIf we loop over a string in Python, we'll get back sub-strings representing each of the characters in that string:
What do you think we'll get if we loop over a
Since
We can also do the opposite of this. We can take an iterable of numbers and turn it into a
Where are bytes objects used in Python?All data that comes from outside of our Python process starts as bytes. But if that data represents text (and Python knows it) Python will convert it to strings automatically. If we use the urllib module in Python to do an HTTP request, the data that we get back is not represented as a string:
The data we get back is represented as a If we open up a file with the mode of
So when we read from that file, the data that we get out of it will not be a string, it'll be a
In fact in this case where we're opening up a

As the Zen of Python says, "explicit is always better than implicit". If for some reason you have a string you want to turn it into bytes, you can call the
Just like
SummaryStrings represent text-based data, while bytes represent binary data (i.e. images, video, or anything else you could represent on a computer). Depending on what you use Python for, you probably won't encounter ✕ ↑ A Python Tip Every Week Need to fill-in gaps in your Python skills? I send weekly emails designed to do just that. How do you write binary data in Python?How to write to a binary file in Python. file = open("sample.bin", "wb"). file. write(b"This binary string will be written to sample.bin"). file. close(). Is binary a data type in Python?Python has the following data types built-in by default. ... 1. Built-in Data Types in Python.. How do you decode a binary text in Python?Method #1: The binary data is divided into sets of 7 bits because this set of binary as input, returns the corresponding decimal value which is ASCII code of the character of a string. This ASCII code is then converted to string using chr() function. How do you convert a binary program to a decimal in Python?Python Math: Convert a binary number to decimal number. Sample Solution:-. Python Code: b_num = list(input("Input a binary number: ")) value = 0 for i in range(len(b_num)): digit = b_num.pop() if digit == '1': value = value + pow(2, i) print("The decimal value of the number is", value) ... .
