Dear Pythonistas (I hope you don't mind that),

studying the data itself but I'm still stumped as to why I keep getting an
error while running the code. I would like answers to this and also any
suggestions as to more elegant ways of solving this problem.
THE CODE
[snipped as it's been mangled, was it posted in html and not plain text
or what? I'm too lazy to unmangle it, others might be kinder]
THE ERROR

The usual way to chase a problem like this is to place print statements
in appropriate places in your code. The for loops in your main function
look like a good starting point to me. Please try that and see what you
come up with.
