Re: [Python-Dev] int() and math.trunc don't accept objects that only define __index__

Another point in favor of the change I just noticed is that int() accept objects defining __index__ as its `base` argument:     Python 3.7.2 (default, Jan 13 2019, 12:50:01)     [Clang 10.0.0 (clang-1000.11.45.5)] on darwin     Type "help", "copyright", "credits" or "license" for more

[Python-Dev] int() and math.trunc don't accept objects that only define __index__

Hi, I open this thread to discuss the proposal by Nick Coghlan in https://bugs.python.org/issue33039 to add __int__ and __trunc__ to a type when __index__ is defined. Currently __int__ does not default to __index__ during class initialisation so both must be defined to get a coherant behavior:
