is a symlink belonging to python@2. You can unlink it:
  brew unlink python@2

To force the link and overwrite all conflicting files:
  brew link --overwrite python

  brew link --overwrite --dry-run python

==> Caveats
Python has been installed as
  /usr/local/bin/python3

Unversioned symlinks `python`, `python-config`, `pip` etc. pointing to
`python3`, `python3-config`, `pip3` etc., respectively, have been installed into
  /usr/local/opt/python/libexec/bin

If you need Homebrew's Python 2.7 run
  brew install python@2

You can install Python packages with
  pip3 install <package>
They will install into the site-package directory
  /usr/local/lib/python3.7/site-packages

Now new terminal windows print

python3: error: unable to find utility "python3", not a developer tool or in PATH

I ran brew unlink python@2, then brew link python, and the error message went away.
