What is "system python"? If I do $ which python I get /usr/bin/python
which points to python 2.7xx. So if everything I added was for python 3
either using pip3 or apt-get would I be adding to "system python"?
I see that most of the "major" python3 modules I had installed, with the
exception of scripy, are in the repository. If I upgraded one of the
repository modules using pip3 would I lose the benefits of installing
from the repository? I know it seems to be possible as I installed pip3
from the repository. The first time I used it to install a module it
informed me there was a more current version available and showed me the
command to update. I updated and it seems to be fine.

A number of years ago I had virtualenv installed. At the time I
remember it took me a while to get it installed and working. Right now I
am working on some scripts to download some financial date using
Selenium and paste it into Libreoffice Calc spreadsheets. Will using
virtualenv have any effect on me running those scripts?
