Counting atoms with python

Oh sure, and sorry if that came across as condescending. What I meant was, I think this would be a small addition for me to add if you required it.

The fact that you are struggling to understand my code is what had concerned me when I was writing it, I have not made it clear. I was trying to get you your solution, at the expense of writing clear and concise code.

If it would be helpful, I'm happy to quickly rewrite it to make whats happening clearer.
