My music player project – Quarantine 19 (started during my quarantine…)

Hi,
This wekend I will try to install again.

  1. First step. Install python 3.5 it is ok this tutorial Python 3

I have installed that version.
Now I have python vers3 and ver 3.5. When I run python3 - - version I receive is python 3.5.2.
Now I am installing the pygame but when I started import pygame from python3 or python 3.5 interpreter I receive : no module named pygame. How should I continue?

Update :also libpeppyalsa.so is not installed in /usr/local/lib when I want to install peppyalsa plugin.
So many issues :frowning:
Thanks
