Python: Encode a string into bytes using base64, then decode it and convert it back to a string

base64encode_decode.py

import base64

base64.b64encode(b'Encode this string.')
#b'RW5jb2RlIHRoaXMgc3RyaW5nLg=='

decodedBytes = base64.b64decode(b'RW5jb2RlIHRoaXMgc3RyaW5nLg==')
print(decodedBytes)
#b'Encode this string.'

decodedString = decodedBytes.decode('utf-8')
print(decodedString)
#Encode this string
