Python (like any modern procedural language) does not have a goto 
command.  You're calling the other function, which means that eventually 
the other function will return back to game().  That's probably a big 
mistake, but it won't matter for the moment.

I don't see any dialog boxes in that code.

Don't paraphrase the effect.  Show just what got displayed.  I've never 
seen an exception called "it can't pull them"

Use of global variables is thoroughly discouraged.  I'd suggest making a 
Game class, and making all these "variables" attributes of an instance 
of Game.  Then you just pass that instance around between the various 
functions, as a formal parameter.
