For a project that I am working on right now, I am required to use Python 3.8.2 specifically. My machine uses 3.11, and I was told that trying to install multiple versions of Python globally could cause other programs to break down.
Luckily, there is something called Pyenv, which is something like nvm for Python. I used the pyenv installed from https://github.com/pyenv/pyenv, after installing other base softwares.
Using pyenv is as simple as running pyenv install 3.8.2 and pyenv versions. I am using PyCharm at the moment, and it can easily be integrated with pyenv.
Another hurray for open source!
