When dealing with purely python packages: always always work in python virtual envs. Conduct these kinds of experiments in separate venvs. If worse comes to worse, a reset consists simply in deleting the venv directory and installing from scratch. If an experiment involves system packages it's a little trickier. You can learn about Docker (which does for the whole system what venv does for python packages), but in most cases you may get away with just taking note of what packages you have installed/uninstalled, so you can revert the process later if needed.
