Broken PyCrust import in wx.shell

[mdickinson]

There's a broken import in the wx Shell class, here:

pyface/pyface/wx/shell.py

Line 195 in 35b57df

from PyCrust.interpreter import Interpreter

PyCrust apparently still exists, and can be installed via a pip install wx_py. But the import will still fail as written: PyCrust isn't a top-level import.

On closer inspection, it looks as though PyCrust is dead, at least on Python 3. The PyPI homepage link is broken, and the wx_py source contains a number of Python 2-isms. A simple import wx_py fails on Python 3 (with ModuleNotFoundError: No module named 'buffer').

Sorry, I'm wrong: the wx_py PyPI package looks dead, but PyCrust is apparently alive and kicking and a part of wxPython. The following brings up a PyCrust shell for me:

Python 3.9.8 (main, Nov  8 2021, 11:51:40) 
[Clang 13.0.0 (clang-1300.0.29.3)] on darwin

>>> from wx.py.PyCrust import App
>>> app = App()
>>> app.MainLoop()
