How to doctest if __name__ already used?

[Leo Breebaart]

I have a simple question (I hope), but one I'd love to get some
feedback on in case I am missing something obvious:

If I have a Python script that is executable, and therefore
already uses '''if __name__ == "__main__"''' to call a function
of its own, what is then the easiest yet still most Pythonic way
to run doctest on the docstrings in the file?

Trigger doctest.testmod() via a "--test" command-line option, is
what I'm thinking. But is that really the best way?

That is what I would have suggested.

If it is just a single standalone script, then yeah, do it that way.
Once your program becomes a few files though, you might want a separate
"test" file that runs doctest.testmod on each of them.
