problems with opening files due to file's path

Okay, so as a response to all of you, I will be using the Entry() widget in
Tkinter to get this path. and the repr() function just makes all my
backslashes 4 instead of just 1, and it still screwes it up with the numbers
and parenthesis is has been since the first post. Oh and I know all about
escape characters, (\n,\b,\a,etc.) I can program C, not a lot, but enough to
know that I like python better. Anyway, so far I tried all of your stuff,
and it didn't work. infact, it puts backslashes in front of the "'" in some
of the words, such as "I'm" goes to "I\'m." So I posted the code I will be
using if you want to see the Tkinter code I can post it, but I don't see how
it will help.
