for this line    if len(words) >= 1:         outp.write(words[0])  

Ugh, look at how that code turned out. Are you using a weird mail client?

You've got the code which reads the first column and writes it away already. All
you need to do is process the data before writing it. So instead of writing
words[0] directly, assign it to a variable, then modify that variable in the way
you need it to be modified and finally write it to outp.
