How do I speed it up? That's a tough one, in general. There are many tricks to speed up Python code; consider rewriting parts in C as a last resort. -In some cases it's possible to automatically translate Python to C or x86 -assembly language, meaning that you don't have to modify your code to gain -increased speed. - -..
