Background: This was homework. It was due last week but as it is past due I am just asking becuase my failure to get this is bugging me. The prof doesn't include much commenting in his grades, and I haven't put any comments in yet as I usually do that at the end(probably a bad practice).

Basically I don't understand why my efforts to automatically play again are failing. When I run this it just automatically completes. The initial while loop should repeat, but I'm never even prompted to re-evalutate the string "play_again".
