Just some thoughts, shouldn't C and Python be used in completely different projects?
X, Y, Z sure, maybe like network card drivers, super computer stuff? I'm sure there's many, I'm sure I even said these back in the day. I stand by my words, I bet python needs to get in there.

I'll have to remember to give this a try.
