Python 等待错误
我试着找一个好的代码行，让Python在执行下一个代码块之前等待，但我找到的都不管用。下面是一个代码示例：
#This is the eighth Question.
print "Q8. What is one of the main bosses in 'Super Smash Brothers Brawl' that is also a boss in 'Kirby the Amazing Mirror?'"
print "1) Krazy hand."
print "2) Mister hand."
print "3) Ganondorf."
print "4) Yoshi."
choice = input("Answer=")
if choice ==1:
print "THAT IS INCORRECT! 'Krazy hand' is SUPPOSED to be spelled 'Crazy hand'!"
print ""
elif choice ==2:
print "INCORRECT! 'Mister hand' is supposed to be spelled 'Master hand'!"
print ""
elif choice ==3:
print "Ganondorf is in the LEGEND OF ZELDA!"
print ""
elif choice ==4:
print "Yoshi isn't in Kirby!!!"
print ""
elif choice> 4 or choice < 1:
print "Go away if you want to fail."
print ""
我希望这个“等待”的代码能在执行下面的代码之前等10秒。
print ""
other = (raw_input("Would you like to continue without choosing a answer?:"))
if other == "yes":
print "Haha! Nicely done! None of those answers were correct! This was a ULTRA QUESTION in disguise!"
print ""
score = score+3
if other == "no":
print "Well, we have to move on anyway. Too bad you didn't say yes......."
print ""
谢谢！任何帮助都非常感谢！

重要声明:
这不是你在这个问题中问的答案，所以请你还是参考Remolten的回复，因为那才是你问的问题的正确答案。
如果你不遵守上面的声明，我会删除我的回答。你被警告了:-D
说完声明后，我查了一下你关于这个游戏的其他两个问题（https://stackoverflow.com/questions/22889223/how-to-prompt-the-user-in-10-seconds-if-nothing-is-entered-in-python-on-mac 和 https://stackoverflow.com/questions/22889477/how-to-ask-a-person-for-input-but-running-a-whole-different-line-of-code-after-5，这两个问题已经被合理地屏蔽了），我想出了一个我确定能满足你需求的代码（我在使用Python 2.7和MacOs X 10.9.2的MacBook Air上测试过）。这段代码是基于这个回答，正如我在对你其他问题的评论中提到的那样，这段代码必须在Mac上工作（而且确实可以）。
我发这个的原因是因为你让我想起了我15年前写的第一个程序。那是一个选择游戏，和你想做的很相似（实际上，我当时也没有调用任何函数:-D），让我感到怀旧。你正在做的事情是个不错的练习，我不希望你因此而气馁。编程非常有趣，而Python是个很好的语言。
请试着理解我发的代码是怎么回事（先查查sys和select模块的文档）。这是提高自己的唯一方法。多上网查资料，阅读，阅读，再练习。
另外，一个很好的工具，可以让别人告诉你如何提高编程技能，就是把你的代码发到https://codereview.stackexchange.com/。在那里创建一个账户，问问如何改进你的代码。
最后一点：
在Stack Overflow（或其他stackexchange.com网站）发问题时，花点时间准确地解释你的问题。像是“不工作...坏了...坏掉了！！给我个解决办法！！”这样的说法对任何人都没有帮助（好吧，你并不是完全这样说的，但你得承认，关于Kirby游戏的第一个问题确实有点让人困惑）。
要记住，S.O.(StackOverflow)是一个非常知名的网站，它的答案很多时候会出现在谷歌的前几条结果中。如果你把问题表述得当，你会得到更好的答案，也能帮助将来遇到同样问题的人。
Stack Overflow上有很多天才（是的，不是我，但我知道有！！）在免费回答大家的问题（我说的是那些在维基百科上有文章的人，明白了吗？）。如果你好好利用，S.O.是个很棒的资源（可以看看这个，这个，并关注一下meta，了解StackOverflow的网络礼仪）。
好了，关于我这些老掉牙的故事就到此为止，下面是代码：
#!/usr/bin/env python
import sys, select
def timeout_input(message, timeout=10):
print "You have %s seconds to answer!" % timeout
if message:
sys.stdout.write(message)
sys.stdout.flush()
i, o, e = select.select( [sys.stdin], [], [], timeout )
if (i):
return sys.stdin.readline().strip()
return ""
# -----
score = 0
# @boatofturtles, put your other 7 questions
# --- HERE ---
# (I didn't want to copy all your code again)
#This is the eighth Question.
print "Q8. What is one of the main bosses in 'Super Smash Brothers Brawl' that is also a boss in 'Kirby the Amazing Mirror?'"
print "1) Krazy hand."
print "2) Mister hand."
print "3) Ganondorf."
print "4) Yoshi."
choice = timeout_input("Answer=", timeout=5)
if not(choice):
print ""
other = (raw_input("Would you like to continue without choosing a answer?:"))
if other == "yes":
print "Haha! Nicely done! None of those answers were correct! This was a ULTRA QUESTION in disguise!"
print ""
score = score+3
if other == "no":
print "Well, we have to move on anyway. Too bad you didn't say yes......."
print ""
elif int(choice) ==1:
print "THAT IS INCORRECT! 'Krazy hand' is SUPPOSED to be spelled 'Crazy hand'!"
print ""
elif int(choice) ==2:
print "INCORRECT! 'Mister hand' is supposed to be spelled 'Master hand'!"
print ""
elif int(choice) ==3:
print "Ganondorf is in the LEGEND OF ZELDA!"
print ""
elif int(choice) ==4:
print "Yoshi isn't in Kirby!!!"
print ""
elif int(choice)> 4 or int(choice) < 1:
print "Go away if you want to fail."
print ""
如果你一开始没有在5秒内提供答案，然后你对问题Would you like to continue without choosing a answer?回答yes，你将会看到以下输出：
Q8. What is one of the main bosses in 'Super Smash Brothers Brawl' that is also a boss in 'Kirby the Amazing Mirror?'
1) Krazy hand.
2) Mister hand.
3) Ganondorf.
4) Yoshi.
You have 5 seconds to answer!
Answer=
Would you like to continue without choosing a answer?:yes
Haha! Nicely done! None of those answers were correct! This was a ULTRA QUESTION in disguise!

如果你想要暂停一段时间，而不执行任何代码：
import time #Put this at the top of the script
time.sleep(10) #Put in the amount seconds
