Searching for pixel color

[michael maver]

Hello, I was just wondering if anyone knew of a way to search the screen for 
a certain color in Python.

I know it is possible to do this in other languages, but I'm not sure how 
I'd go about doing this in Python. Just to let you know, I'm running windows 
XP and I don't really need it to be a cross platform solution, but if it was 
that'd be an extra bonus.

Thanks very much for taking the time to read this and, hopefully, respond!
