I seem to have two versions of python 3.7.9 installed

[miner_tom]

I apologize, but I do not understand. I installed requests but have no idea what to use it for. Looking at the documentation is says that it is "HTTP for humans".

I have pip and use pip -v and that just brings up a list of commands that I can use with pip. pi -V shows the version of python that it points to, which is python 3.7

I still do not know the difference between what typing "python" and typing "python3" is. Or, to where does each one point?

Thank You
Tom
