Nick, you have now spent 4 days arguing over a minor coding problem that 
you were given solutions to on the first day, primarily because you feel 
that the solutions you are being offend some programming aesthetic you 
have.

I suggest that it's time for you to re-evaluate what you want from this 
ng, and indeed what language you want to code in if your perl "minimal 
code possible" aesthetic is so important to you.

If you want good python code, then stop telling everyone here that their 
working solutions are wrong and should be more like your dysfunctional 
code, and use the solutions you are given.

If you want to write minimalist perl code, then stop using python and use 
perl.

In either case, you need to stop arguing with people who are offering you 
solutions to your problems solely based on the fact that you don't like 
their coding styles.

You are the one who comes here asking for solutions. Either accept the 
solutions you are offered, or stop asking for them.
