[WxPython] NameError: global name 'PyAssertionError' is not defined

[Yoriz]

Ok I was thinking you wanted help with fixing the error.
PyAssertionError is not a built in python error its a wx python specific error, so you need to put wx. infront of it.

>>> import wx
>>> wx.PyAssertionError
<class 'wx._core.wxAssertionError'>
