Python has been installed as

#{HOMEBREW_PREFIX}/bin/python3
|
|
|
|
Unversioned symlinks `python`, `python-config`, `pip` etc. pointing to
|
|
`python3`, `python3-config`, `pip3` etc., respectively, have been installed into
|
|
#{opt_libexec}/bin
|
|
|
|
You can install Python packages with
|
|
pip3 install <package>
|
|
They will install into the site-package directory
|
|
#{HOMEBREW_PREFIX/"lib/python#{version.major_minor}/site-packages"}
|
|
|

tkinter is no longer included with this formula, but it is available separately:
|
|
brew install python-tk@#{version.major_minor}
