I'm trying to follow Python's best practice for environment settings as described below. https://averlytics.com/2017/08/06/virtual-environment-a-python-best-practice/
The whole point of the article is to install packages only in a virtual environment and avoid installing any other things on the system. I tried to follow this practice by completely deleting Pycharm, Anaconda, Python and re-installing them from scratch.
After then, I've always tried to set up virtual environment on Pycharm (venv) to do my work.
However, I think I made a mistake or two by pip install ... on default terminal, which resulted in system installed packages again.
I really wanna get back on track of best practice installation but don't wanna go through whole uninstall and reinstall process.
I checked pip list on my PowerShell but I can't tell which one I should leave and which one I should uninstall, because maybe there are some packages that keep my Anaconda and Pycharm and the whole things working. I don't wanna make another problem out of this one.
What should I do? Is it too late and better off just leaving them as they are? Is "keeping minimal system installation and do all the installation on virtual environment" thing still valid as of now?
I wish somebody had taught me better than installing Python and using IDLE in the first place.
Here are the list of installed packages.
