[Tutor] role playing game - help needed

[Al Stern]

Peter, Thanks for the advice as to how to use numbers.  I had learned this
before but the example in the documentation didn't use 'int' so I thought I
didn't need to when using dictionary values.

Anyway, I finally finished the program.  I am sure it isn't the most
efficient code and I suspect I should have used the 'while' loop earlier,
but the bottom line is it seems to work.  I will paste what I came up with
in case anyone is interested.

Thanks again to everyone.  I couldn't have done it wothout you.
