def safe_base64_decode(s): if len(s)%4 != 0: s = s+ b'=' return safe_base64_decode(s) else: return base64.b64decode(s)

测试:

assert b'abcd' == safe_base64_decode(b'YWJjZA=='), safe_base64_decode('YWJjZA==') assert b'abcd' == safe_base64_decode(b'YWJjZA'), safe_base64_decode('YWJjZA') print('ok')

ok
