[Tutor] ideas on how to process a file

[Spencer Parker]

Oh...nice...this makes things much easier than what I had before.

I mainly used writelines because I couldn't figure out why it was only
writing one line.  Then I did and never took out the writelines...I just did
and it works just fine for the most part.

Thanks again for the help.
