我正在努力通过 Zed Shaw 的 LPTHW，我在（新）练习 43 额外学分 3 中遇到了障碍。
所以在这里我试图创建一个函数，打印另一个函数，它是一个大的文档字符串。
这里是引擎
class Game(object):
def __init__(self, start):
self.quips = [
"You died. You kinda 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_room_name is taken from init argument start
next_room_name = self.start
while True:
print "\n--------"
# set variable room to get function from next_room_name
room = getattr(self, next_room_name)
# unpacks function from next_room_name into room
next_room_name = room()
room = current_room
print current_room.__doc__
这是我试图调用来启动游戏的一些函数。
def central_corridor(self):
"""
The Gothons of Planet Percal #25 have invaded your ship and destroyed
your entire crew. You are the last surviving member and your last
mission is to get the neutron destruct bomb from the Weapons Armory,
put it in the bridge, and blow the ship up after getting into an
escape pod.
You're running down the central corridor to the Weapons Armory when
a Gothon jumps out, red scaly skin, dark grimy teeth, and evil clown costume
flowing around his hate filled body. He's blocking the door to the
Armory and about to pull a weapon to blast you.
"""
action = raw_input("> ")
if action == "shoot!":
print "Quick on the draw you yank out your blaster and fire it at the Gothon."
print "His clown costume is flowing and moving around his body, which throws"
print "off your aim. Your laser hits his costume but misses him entirely. This"
print "completely ruins his brand new costume his mother bought him, which"
print "makes him fly into an insane rage and blast you repeatedly in the face until"
print "you are dead. Then he eats you."
return 'death'
elif action == "dodge!":
print "Like a world class boxer you dodge, weave, slip and slide right"
print "as the Gothon's blaster cranks a laser past your head."
print "In the middle of your artful dodge your foot slips and you"
print "bang your head on the metal wall and pass out."
print "You wake up shortly after only to die as the Gothon stomps on"
print "your head and eats you."
return 'death'
elif action == "tell a joke":
print "Lucky for you they made you learn Gothon insults in the academy."
print "You tell the one Gothon joke you know:"
print "Lbhe zbgure vf fb sng, jura fur fvgf nebhaq gur ubhfr, fur fvgf nebhaq gur ubhfr."
print "The Gothon stops, tries not to laugh, then busts out laughing and can't move."
print "While he's laughing you run up and shoot him square in the head"
print "putting him down, then jump through the Weapon Armory door."
return 'laser_weapon_armory'
else:
print "DOES NOT COMPUTE!"
return 'central_corridor'
这是它在主程序中的调用方式
a_game = Game("central_corridor")
a_game.play()
但我得到的只是

编辑：为了成功完成练习，我需要编辑引擎以打印出文档字符串，而不是编辑函数。
