      Error=To install Python packages system-wide, try brew install
       xyz, where xyz is the package you are trying to
       install.

       If you wish to install a Python library that isn't in Homebrew,
       use a virtual environment:

         python3 -m venv path/to/venv
         source path/to/venv/bin/activate
         python3 -m pip install xyz

       If you wish to install a Python application that isn't in Homebrew,
       it may be easiest to use 'pipx install xyz', which will manage a
       virtual environment for you. You can install pipx with

         brew install pipx

       You may restore the old behavior of pip by passing
       the '--break-system-packages' flag to pip, or by adding
       'break-system-packages = true' to your pip.conf file. The latter
       will permanently disable this error.

       If you disable this error, we STRONGLY recommend that you additionally
       pass the '--user' flag to pip, or set 'user = true' in your pip.conf
       file. Failure to do this can result in a broken Homebrew installation.

       Read more about this behavior here: <https://peps.python.org/pep-0668/>

    <<~EOS
      Python is installed as
        #{HOMEBREW_PREFIX}/bin/python#{version.major_minor}

      Unversioned and major-versioned symlinks `python`, `python3`, `python-config`, `python3-config`, `pip`, `pip3`, etc. pointing to
      `python#{version.major_minor}`, `python#{version.major_minor}-config`, `pip#{version.major_minor}` etc., respectively, are installed into
        #{opt_libexec}/bin

      If you do not need a specific version of Python, and always want Homebrew's `python3` in your PATH:
        brew install python3

      `idle#{version.major_minor}` requires tkinter, which is available separately:
        brew install python-tk@#{version.major_minor}

      #{dbm_is} available separately:
        brew install python-gdbm@#{version.major_minor}
