Dear Sir:



For whatever reason I have lost functionality of using Python 3.11. While opening Python (standalone or from CMD prompt) as usual this AM the
following message appeared. Did read that it is not compatible with
Windows but I can't get it to work as I don't know what module will load.

If you can help great.

Looking at PyPI, it appears that it was last supported on Python 3.5.

I'd suggest that after uninstalling Python, you delete the Python folder
if it's still there (because of any installed 3rd-party modules) before re-installing.

(*) How to patch it

Open the file

Lib/site-packages/pyreadline/py3k_compat.py

and locate the procedure

def callable(x):
return isinstance(x, collections.Callable)

Change it to

def callable(x):
return isinstance(x, collections.abc.Callable)

You're done.

there is a pyreadline3

I tried it for a particular case and didn't have a whole lot of luck
with it, so YMMV, but somebody has done the porting work to keep it more current.
