> If this is intended behaviour, which seems to be the case according to ncoghlan's comment https://bugs.python.org/issue32230#msg307721, it should be clearly documented, as it's rather frustrating. The -b command line documentation is not explicitly enough? "Issue a warning when comparing bytes or bytearray with str or bytes with int. Issue an error when the option is given twice (-bb)." https://docs.python.org/dev/using/cmdline.html#cmdoption-b Modifying warning filters don't change how Python emits or not warnings. It only changes how emitted warnings are handlded: ignored, displayed, treated as errors. The relationship between -b and BytesWarning is different than other warnings. Should we add a note near the BytesWarning documentation? https://docs.python.org/dev/library/exceptions.html#BytesWarning
