Need help on a program.

[Doug Stanfield]

With this:

> IOError: [Errno 2] No such file or directory: 'p7.dat'

Python is telling you it can't find a file with that name.  This means the
file is either not there or its looking in the wrong place.  Assuming you've
put that file in the same place as your program, try to change the open
statement on line 37 to be (untested):

        infile = open(r"C:\Jim's Stuff\College Stuff\CS120\Python
Programs\p7.dat", "r")

That (or something like it) tells Python exactly where the file is.  At some
point you should start to look at what you have in your PATH environmental
variable and figure out where it thinks it should be looking.
