Some of my Python code which was running without any issue fails
miserably with F34. Python is now version 3.9, I found some building
bugs for 1 of the libraries which has been fixed earlier this year.
Namely I have issue with urllib3 and pexpect. Where should I ask
about it? I feel this list is not really about Python issues, and
that code was working fine with Python 3.8.
The best place to look for these things is at python.org. A quick
search found this page with changes from 3.8 to 3.9.
https://docs.python.org/3/whatsnew/3.9.html
It has this to say about urllib.
urllib.parse
Earlier Python versions allowed using both ; and & as query parameter
separators in urllib.parse.parse_qs() and urllib.parse.parse_qsl(). Due
to security concerns, and to conform with newer W3C recommendations,
this has been changed to allow only a single separator key, with & as
the default. This change also affects cgi.parse() and
cgi.parse_multipart() as they use the affected functions internally.
For more details, please see their respective documentation.

It has nothing to say about pexpect. So, pexpect is not a
python provided program, and probably uses something on that page
internally that has changed.

Hi and thank you!
Actually Felix from the devel list 'smelled' the issue right away: I
install libraries through pip without a virtual environment. I should
either used rpm packages or create venv and use pip for that environment.
He even told me how to clean up everything and get running.
As an addon, the pexcept issue which was there right before my email to
the list, fixed itself when I emailed devel and want to write the exact
error message. So go figure!
Anyway I learned something and I guess I am a better(?) Python
programmer now ;-)
Thank you all for helping.
Fred
