how does ECPrivateKey work?

[telejoshi]

Looking into learning python right now and think it's a great project to have an insight.

Anyway I'm curious what exactly ECPrivateKey function does. It's being imported and used as a function in Btcbf. I'm aware how includes work in Java (I can use functions of a library to work with). Where can I find the code?

My motivation was: does it randomly generate private keys by starting with random numbers or does it find the same keys over and over again when we start this program?

Thanks guys!
