I am currently coding a 'text-based adventure game', and im having a bit
of trouble with while loops. Here is my code so far:
Please paste in the traceback you're getting, and please set your mail
client program for plain text when posting. What I see here has the
indentation stripped out of your script so that before I can even test
your code I'll have to guess at how you have it indented, and I'm more
likely than you to get it right and may inadvertently fix your bug and
never know it even before getting a chance to see the bug.

For some reason that I cant figure out, the 'Player creation loop' wont
run when I try to run the program. When I try to run it in IDLE, nothing
happens, Any help is much appreciated.
