Python

about installing python right: use pyenv apparently

‌brew install pyenv
pyenv install 3.8.3 pyenv global 3.8.3

and be sure to add this to the ~/.zshrc:

if command -v pyenv 1>/dev/null 2>&1; then
  eval "$(pyenv init -)"
fi

now source .zshrc or restart your terminal and voilá python and pip versions are managed by pyenv making it all manageable.
