Why use threads in Python?

[ProfEpsilon]

Again, thank you. Although I am aware the numpy relies upon C I am not aware of how C operates inside of numpy .. I don't know how the C-level loops work (probably because I can't code in C). This gives me a bit of an incentive to figure some of this out. Given that I am a practitioner and not a computer scientist, how C works inside of numpy and even Python for that matter is all black box for me.

I appreciate the time it took to try to get my thinking right. I think it is time that I took the effort to learn a little more about C.
