Bug report
With the following class hierarchy:
classA0:def__new__(cls,*args,**kw):returnsuper().__new__(cls)def__init__(self,*args,**kw):super().__init__()classA1(A0):def__init__(self,a,b):super().__init__()self.a=aself.b=bclassA2(A1):c=None
help(A2) shows the wrong signature for instantiating A2 asA2(*args, **kw) instead of the expectedA2(a, b), despite the fact that is shows the correct signature for__init__:
Help on class A2 in module __main__:class A2(A1) | A2(*args, **kw) | | Method resolution order: | A2 | A1 | A0 | builtins.object | | Data and other attributes defined here: | | c = None | | ---------------------------------------------------------------------- | Methods inherited from A1: | | __init__(self, a, b) | Initialize self. See help(type(self)) for accurate signature. | | ---------------------------------------------------------------------- | Static methods inherited from A0: | | __new__(cls, *args, **kw) | Create and return a new object. See help(type) for accurate signature. | ...Note thathelp(A1) works correctly and shows the correct signature asA1(a, b):
Help on class A1 in module __main__:class A1(A0) | A1(a, b) | | Method resolution order: | A1 | A0 | builtins.object | | Methods defined here: | | __init__(self, a, b) | Initialize self. See help(type(self)) for accurate signature. | | ---------------------------------------------------------------------- | Static methods inherited from A0: | | __new__(cls, *args, **kw) | Create and return a new object. See help(type) for accurate signature. | ...This doesn't seem to be an issue if__new__ is not defined on A0, or if A1 redefines__new__ with the same signature as__init__.
