What this does is open the file once for every string in 'm', and read
through it. But you increment i for every line in the file, that's why
you're having problems.
I think you probably want to open the file once and iterate over it,
but you'll need to figure out what you're trying to do before you can
figure out how to do it in Python :)
Also, be up-front about homework assignments. Honesty won't hurt you
(since we can all tell anyway), and it means we know you're trying to
learn, not to cheat. And yes, there are a discouraging number of
people who do try to cheat, so setting yourself apart from them is
well worth it. :)
