def onFaceDetected(self, *_args):

from this tutorial, what is the meaning of *_args as a parameter to a Python module's method?

I've seen lots of explanations for just an asterisk or just an underscore, but not both.

The underscore is just part of the name, no special meaning here at all. The `*` syntax doesn't dictate a name, you could use `*foobar` or `*__super_sekret` for all Python cares. – Martijn Pieters Jul 02 '15 at 20:14

In this case I'm guessing the author wanted to convey that the extra arguments are being ignored. – Martijn Pieters Jul 02 '15 at 20:16
