Hey, I have a problem. I was presented a problem where I need to open a file and then copy and rename it. We are still using really basic commands, but I am pretty lost with this. I know how to open a file and get python to read it. Any help would be great.

I'd like to convert a little endian hex string: '00020000020000FC' to a number.
