New submission from Eric Fahlgren <[email protected]>:
Windows 10 Pro 64
Python 3.8.3 64
wxPython 4.1.0
It appears that there are synthetic classes in the mro, which don't appear in
the type's namespace, raising KeyError when encountered. From reading the
function's doc and source, it looks like it should handle this internally and
return a valid dict (possibly empty), and not raise KeyError.
>>> import typing, wx
>>> typing.get_type_hints(wx.Window)'
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "C:\Program Files\Python38\lib\typing.py", line 1223, in get_type_hints
base_globals = sys.modules[base.__module__].__dict__
>>> wx.Window.mro()
[<class 'wx._core.Window'>, <class 'wx._core.WindowBase'>, <class
'wx._core.EvtHandler'>, <class 'wx._core.Object'>, <class
'wx._core.Trackable'>, <class 'sip.wrapper'>, <class 'sip.simplewrapper'>,
<class 'object'>]
KeyError: 'sip'
