Python has a tk output to keep the python package small.
- If you're using tk for a personal script, you will probably need run 'guix
install python2:tk'
- If you need tk for a package input, you will need to use
'("python2-tk" ,python "tk")' or copy the input from one of the python
packages that uses tk.
