拖欠了好几天了，今天抽空敲了个练习，周末有空一定得把这周的任务完成了。

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)
