While Loops

We developed several variants of the program, with source code as follows:

• guessA.py
  Our initial version. It is structured with a fake first guess to get into the main while loop, with the real user input chosen immediately within the loop body.
• guessB.py
  A revision of our first version where we ask for the first guess before the loop, and then ask for each subsequnt guess at the end of each iteration of the body. We also demonstrate that the congratulatory message could be done after the loop body (we could have made such a change in the first version as well).
• guessC.py
  This uses the basic structure from "guessB" version, but this time wraps that logic in an outer while loop that manages the dialog for allowing the user to play multiple rounds of the game within a single execution of the software.
• guessD.py
  Identical logic to "guessC" except we gave a previous of the use of user-defined functions to better organize source code. Instead of having the inner process coded directly nested in the outer loop, we have defined a playRound() function and then make a call to that function from within the broader loop.
