from sys import exit
def gold_room():
print "This room is full of gold. How much do you take?"
next = raw_input("> ")
if next.isdigit():
how_much=int(next)
else:
dead("Man, learn to type a number.")
if how_much < 50:
print "Nice, you're not greedy, you win!"
exit(0)
else:
dead("You greedy bastard!")
def dead(why):
print why, "Good job!"
exit(0)
