I have a suggestion for an API, how about a keyword argument to "abstractmethod" that allows to set the abstract method as "optional" meaning that sub-implementations can either implement their own version or use the ABC's own, infact, I think the STDLIB could use this itself (I haven't looked at the stdlib entirely).
For native code, a new method flag would be required, probably something like "OPTIONAL_ABSTRACT" (I forget the naming convention for flags) example: @abstractmethod(True) # Method won't be included in required implementations. Default: False (for bcompat reasons) _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/DPQAXKN2NSZYFTEHAGEXHWCTPSDWD4B4/ Code of Conduct: http://python.org/psf/codeofconduct/
