通过LPTHW工作，并坚持练习41的额外功劳：
额外信用：
- 为游戏添加作弊码，以便您可以越过困难 室。
- 不要让每个功能都打印出来，而是要了解“doc 字符串“样式评论。将房间描述写为文档评论， 并更改跑步者以打印它们。
- 一旦您将文档评论作为房间描述，您需要吗？ 甚至有功能提示？让跑步者提示用户，并且 将其传递给每个函数。你的功能应该是 if-statements打印结果并返回下一个房间。
据我所知，到目前为止使用像这样的文档字符串是不受欢迎的，但这就是我想出的：

在靠近底部的跑步者功能中，我想添加'elif room == death：'位可以正常工作，它只是挂起等待raw_input（）然后打印随机'quip'，因为它应该在我按ENTER键。有人能帮我理解我错过的东西吗？任何帮助表示赞赏！
修改的 感谢一些照明快速反馈这是我所拥有的，虽然rocksportrocker的解决方案更简单：
def runner(themap, start):
next = start
while True:
## Global variable in order to pass prompt value to rooms
global globvar
room = themap[next]
## Room dependent prompts
if room == laser_weapon_armory:

print room.__doc__
prompt = raw_input("[keypad]> ")
elif room == escape_pod:
print "\n--------"
print room.__doc__
prompt = raw_input("[pod #]> ")
elif room == the_bridge:
print "\n--------"
print room.__doc__
prompt = raw_input("> ")
elif room == central_corridor:

print room.__doc__

else:
pass
## Set raw_input from prompt to Global variable (globvar)
globvar = prompt
next = room()
答案 0 :(得分：3)
death没有文档字符串。如果room==death则print room.__doc__打印None。在下面的if / elif中你从函数runnner返回导致程序结束。
如果您添加了缺少的文档字符串，并且您使用简单的“return "death"”替换了runner()中的pass，或者通过省略相应的elif，您的程序将会正常运行子句。
