At a glance it doesn't seem like the Python code uses anything that's terribly difficult in C#. What parts are you having trouble with? Do you know both Python and C#?

I don't know much python i got this from the internet and i would like to copy it and translate it to c# but i can't seem to work it out.

Sounds like a good time to learn a little Python. :) No offense, but even though the program is short, I'm not sure anyone will be willing to do the conversion for you. If you have specific questions like which libraries correspond to each other between languages or specific problems/errors you're seeing, that's fine.

The bear will be in the import modules

Nah, they're all pretty universal as far as features go. C# (.NET rather, and probably Mono) support all of them in some form or another.
