Get the Program!

This is my cryptogram game I made with Python. I love puzzles and one type of puzzle I like is a good cryptogram. This was mainly an exercise to see if I could make one of these puzzles. It really made me think and plan. If I pulled it off, I get a fun toy. And I did. I'm sure I put a readme file in there that tells you how to make your source information. The program reads the source and scrambles it so it is ready to solve.
I simply read in the source. I initialized the alphabet and made a scrambled version each time the program is run called encryptabet. It's really just a scrambled alphabet. I also dynamically display the puzzle at the top and the guesses below. Unguessed items are initialized with a dash.
