Loading kube-config - issue with python base64.b64decode() function #128

This script uses base64.b64decode() function to decode 'id-token' from kube-config file.

Even though my base64 string is ok( Golang API decodes it without any issue),
the python decoder always returns 'incorrect padding' error message. I have tried with PY3.5, PY3.7 and PY3.8, none works.

Here is my base64 string:
