Hi Ryan,

By "doesn't work", what happens?  Do you get an error message, or ...?
The more details here the better, since we really are not sure what the
cause of the problem is yet.

This looks somewhat suspicious.  pickle files are meant to be stored in
binary files, so you may need to open the file in binary mode:

    pickle_file = open("dictionary.dat", "rb")

Otherwise, bad things may happen, especially on Windows platforms.


Good luck to you!
