所以我知道这个网站有太多关于Zed Shaw的学习Python困难的问题，但是我要经历ex42。，额外的学分＃3，让我挂断了。
我无法让类引擎有效地启动并转换到类Map中，游戏可以开始通过我定义的不同函数
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，而是从类Engine转换到类Map，因此游戏可以继续。它要么不在类Engine中定义'Map'，要么在我最后设置的变量中定义'Map'并尝试使用play（）命令运行。
您可以指出我关于课堂互动的任何其他链接都会很棒。 thnx再次

这里有很多错误。
您显示的代码是非法缩进的;看起来__init__()和play()应该缩进为类Engine的成员，death()和princess_lives_here()缩进Map。
类的__init__在每一端都需要双下划线而不是单个下划线。
该行：
e = "princess_lives_here".Map.Engine
是荒谬的蟒蛇;它首先尝试在字符串中查找“Map”属性。如果你想要实例化一个类的新对象，你会说
e = Engine( "princess_lives_here" ) # or Map( "...")?
我不清楚你需要Map和Engine，但我猜你要么想要Map是Engine的子类（Engine对所有游戏都是通用的，而Map是特定于这个游戏的）或者你想要它们作为单独的对象，其中引擎和地图互相引用。
目前，您将Engine作为Map的子类。如果它们应该是分开的，则将Engine声明为对象，让其__init__同时获取起点和地图实例，然后执行
m = Map()
e = Engine( m, "princess_lives_here" )
