clean up python versions mac osx

Question

I tried to run a python script on my mac computer, but I ended up in troubles as it needed to install pandas as a dependency.

I tried to get this dependency, but to do so I installed different components like brew, pip, wget and others including different versions of python using brew, .pkg package downloaded from python.org.

In the end, I was not able to run the script anyway.

Now I would like to sort out the things and have only one version of python (3 probably) working correctly.

Can you suggest me the way how to get the overview what I have installed on my computer and how can I clean it up?

Thank you in advance

Use brew list to see what you've installed with Brew. And Brew Uninstall as needed. Likewise, review the logs from wget to see where it installed things. Keep in mind that MacOS uses Python 2.7 for system critical tasks; it's baked-into the OS so don't touch it.

Anything you installed with pip is saved to the /site-packages directory of the Python version in which you installed it so it will disappear when you remove that version of Python.

The .pkg files installed directly into your Applications folder and can be deleted safely like any normal app.
