Exception Handling

You decide to upload your recent project to a programming community website for feedback, and one thing that community users keep pointing to is the lack of exception handling. Realizing that they are correct, you decide to rectify the situation and improve your programs or at least one of them. Take one of the programs you designed over the past couple of weeks and enhance the program with exception handling code. Your program should incorporate the TRY and EXCEPT blocks and handle any errors and exceptions that you can find.

For this project:

You will submit your python code in either the original .py file, or copied into a .txt file.
