Sometimes it’s interesting using virtual environments to develop. One different version of version installed in SO is enough. In Python exists the virtualenv. In these virtual environment it’s possible use the version by project independent of SO.
Let’s code:
python3.8 -m venv myvenv
By default venv would be installed in your SO. If not just, in Ubuntu:
sudo apt-get install python3-venv
Now, the new folder was created. Just activate the virtualenv:
source bin/activate
Done. Now just use python in virtualenv.
and that’s all folks!
