f __sizeof__(...) ...

f __format__(...) ...

This is invoked early on by abc.ABCMeta.__subclasscheck__(). It should return True, False or NotImplemented. If it returns NotImplemented, the normal algorithm is used. Otherwise, it overrides the normal algorithm (and the outcome is cached).

f __init__(...) ...

x.__init__(...) initializes x; see help(type(x)) for signature
