1# Based on MicroPython config option, comparison of str and bytes 2# or vice versa may issue a runtime warning. On CPython, if run as 3# "python3 -b", only comparison of str to bytes issues a warning, 4# not the other way around (while exactly comparison of bytes to 5# str would be the most common error, as in sock.recv(3) == "GET"). 6# Update: the issue above with CPython apparently happens in REPL, 7# when run as a script, both lines issue a warning. 8print("123" == b"123") 9print(b"123" == "123") 10
