Emily Zhao added the comment: Might be worth making this addition from 3 (I'm not sure how to add this to 2) -b : issue warnings about str(bytes_instance), str(bytearray_instance) and comparing bytes/bytearray with str. (-bb: issue errors) Building on Martin's example: On all of these, python2 is Python 2.7.6 (default, Apr 6 2014, 23:14:26) [GCC 4.2.1 Compatible Apple LLVM 5.1 (clang-503.0.38)] on darwin Type "help", "copyright", "credits" or "license" for more information. emily-mba:cpython emily$ python2
bytearray("3") == u"3" False
emily-mba:cpython emily$ python2 -b
bytearray("3") == u"3" __main__:1: BytesWarning: Comparison between bytearray and string False
emily-mba:cpython emily$ python2 -bb
bytearray("3") == u"3" Traceback (most recent call last): File "<stdin>", line 1, in <module> BytesWarning: Comparison between bytearray and string
