Funny error message

[Bob van der Poel]

It appears that a couple of things are happening ... and not being a python
install expert by a long shot, none of it makes sense to me.

But, let me first state that I've never screwed around with the python
installation. I let the Ubuntu packager take care of that.

- running "python -v" I get A LOT of data about various modules being
loaded, etc. I see that most of the modules are loaded from the system dir
/usr/lib/python3.8 but some from .local/lib/python3.8. I have never created
the .local tree so I, again, assume that the installer is doing this. BTW,
sys.path is:
['', '/usr/lib/python38.zip', '/usr/lib/python3.8',
'/usr/lib/python3.8/lib-dynload', '/home/bob/.local

   /lib/python3.8/site-packages', '/usr/local/lib/python3.8/dist-packages',
'/usr/lib/python3/dist-packages']

- running python -v gives too much info. I really can't see what is causing
the unneeded text, but assume it is "requests". Note that this is the
module from .local. Experimenting, I deleted .local/.../requests and it is
now using /usr/.../requests. I've undeleted the .local version.

- creating a one line script with only a bad command in it and running
"python -v script.py >err_file" does not give the lengthy printout. The
same error message is displayed on the terminal.

I really have no idea ... and don't care that much, except it is annoying
to have these same lines repeated over and over again after every error.
Could this be a bug in requests?
