python可以参加的比赛_参加两级比赛

所以我知道这个网站上有太多关于Zed Shaw的《艰难的学习Python》的问题，但是我正在经历ex42，Ex credit 3，让我挂断了电话。在

我很难让类引擎有效地启动并转换到类映射中，在这里游戏可以开始执行我定义的不同函数

代码如下：from sys import exit

from random import randint

class Map(object):

def death():

print quips[randint (0, len(quips)-1)]

exit(1)

def princess_lives_here():

print "You see a beautiful Princess with a shiny crown."

print "She offers you some cake."

eat_it = raw_input(">")

if eat_it == "eat it":

print "You explode like a pinata full of frogs."

print "The Princess cackles and eats the frogs. Yum!"

return 'death'

elif eat_it == "do not eat it":

print "She throws the cake at you and it cuts off your head."

print "The last thing you see is her munching on your face. Yum!"

return 'death'

elif eat_it == "make her eat it":

print "The Princess screams as you cram the cake in her mouth."

print "Then she smiles and cries and thank you for saving her."

print "She points to a tiny door and says, 'The Koi needs cake too.'"

print "She gives you the very last bit of cake and shoves you in."

return 'gold_koi_pond'

else:

print "The Princess looks at you confused and just points at the cake."

return 'princess_lives_here'

class Engine(Map):

def _init_(self, start):

self.quips = [

"You died. You suck at this.",

"Your mom would be proud, if she were smarter",

"Such a luser.",

"I have a small puppy that's better at this."

]

self.start = start

def play(self):

next = self.start

while True:

print "n-----"

room = getattr(self, next)

next = room()

e = "princess_lives_here".Map.Engine

e.play()

现在问题不在于Map类中的其他函数，而是如何从类引擎转换到类映射，这样游戏才能继续。它要么没有在类引擎中定义'Map'，也没有在我最后设置的变量中定义'Map'，并尝试使用play()命令运行。在
