My first question is what does this look like when print() and some_func() have other parameters?  In other words, what would this look like?

     print('hello', name, some_func('whatsit', another_func('good-bye')), sep=' .-. ')

Currently, I would format that as:

    print(
         'hello',
         name,
         some_func(
              'whatsit',
              another_func(
                  'good-bye')
                  ),
               ),
         sep=' .-. ',
         )

Okay, maybe a few more new-lines than such a short example requires, but that's the idea.
