Dave:

You've done a good job of re-posting (my) code from
http://aspn.activestate.com/ASPN/Mail/Message/1225515 as
your own work. Yes, you changed two "int"s to "float"s and
added a "c:/" to the "open" call, and removed the "def main():",
but that's about it.

Good luck with your homework. Let's see, that would be "OPIM
101: Introduction to Computers as Analysis Tools" at the Wharton
School, University of Pennsylvania. See also
http://opim-web.wharton.upenn.edu/home/coursedes.html#OPIM101

Next time, you might just ask for help at opim-help at wharton.upenn.edu

One of the stated aims of that course is "Build student skill and
comfort using the computer to solve problems"; I don't
think that they mean for you to use the computer to find
others to do your work for you.
