I had a good python environment, which got wrecked by MacOS updated which broke Anaconda. I reinstalled Anaconda, but it's still a bit of a mess, where some python kernels for Jupyter Notebooks aren't found, and the system tries to find Python in anaconda3 folders which no longer exist. I tried to fix it which might have made it even messier.
Is there a way I can uninstall everything related to anaconda/python, so that I can just reinstall python3 from scratch?
