Can you post some sample code that you've written to show that you've
actually tried by yourself first?  That will also give us a starting
point in helping you.

Otherwise we're likely to be spoonfeeding you answers to your homework
assignment.  Presumably you have already learned some basic programming
in class and are supposed to be trying to apply that learning in this
exercise?

Hints: How do you open a file in Python and read lines from it?  (see
the tutorial online at www.python.org)  How do you define an "array"
in Python?  (see tutorial again, looking at dictionaries)  How do you
write a loop in Python?  (use the 'for' or 'while' keywords, depending
on what exactly you want to do: see the tutorial for examples)
