Add missing padding when decoding base 64 in Python

decode_base64_without_padding.py

"""
Sometimes we got base64 string without padding and python can't decode it as it is.
We have to add missing paddings and here is the code.

Especially, JWT token contains Base64 string withoug padding,
where padding must not added.

import base64

text = 'c2FtcGxlIQ'
text += '=' * ((4 - len(text) % 4) % 4)
result = base64.b64decode(text).decode()
print(result)

# If you need a function:
#
# def decode_base64(text):
#     import base64
#
#     text += '=' * ((4 - len(text) % 4) % 4)
#     return base64.b64decode(text).decode()
