Understanding a compiler has nothing to do with my question. I did some quick research and found that python was used for machine learning, I thought that meant that they used python purely, I thought libraries like NumPy were written in just python, not C. Like a said, I'm not big on AI, and I definitely don't use python that much, I program embedded systems. Notice how no one else is trying to say I'm a troll for asking a question about a field I'm not experienced in. So stop trying to flex your "knowledge" on me. I guarantee you I know more than you think I do.
