Convert bytes to string in Python

This post will discuss how to convert bytes to a string in Python.

1. Using `decode()` function

The idea is to use the bytes.decode() function for decoding the given bytes to return a string. It takes the encoding used to encode the data to bytes. If no encoding is specified, the utf-8 encoding is applied.

import sys

if __name__ == '__main__':

b = b'abc'

encoding = sys.getdefaultencoding()

s = b.decode(encoding)

print(s) # abc

2. Using String constructor

Alternatively, you can use the string constructor str(data, encoding) to get a string decoded from the given bytes using the given encoding.

if __name__ == '__main__':

b = b'abc'

encoding = 'utf-8'

s = str(b, encoding)

print(s) # abc

3. Using `map()` function

You can get the string constructed from the bytes array by mapping each byte to a character using the chr function. Here’s what the code would look like:

if __name__ == '__main__':

bytes_data = [97, 98, 99]

s = ''.join(map(chr, bytes_data))

print(s) # abc
