Python Python is not compatible between versions, so it is desirable to be able to switch between versions as needed. You can use Anaconda or pyenv for version control, but it's not recommended to have them on the same machine. The introduction method of pyenv is explained below.

pyenv A tool that makes it easy to switch between python versions.

brew install pyenv

echo 'eval "$(pyenv init -)"' >> ~/.bach_profile
