adding_machine

A simple adding machine with user prompts.

What does it do?

A few basic functionalities that are covered in this sample:

• Requests user input via input()
• Sets an initial state and allows the user to update the state at the end of a while loop, thereby making it possible to re-run the program if desired
• handles exceptions using try/except/else statements
  • forces the user to input an integer
  • prompts the user if there is an exception
  • updates the state of the while-loop-within-a-while-loop if there are no exceptions, thereby allowing the program to pass into the next phase of the program
