Python等待错误

Question

我试图找到一个好的代码行，让 python 在执行下一个代码块之前等待，但没有发现任何工作。这是下面的代码示例：

#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“等待”代码在执行下面的代码之前等待 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！非常感谢所有帮助！

Answer 1

如果你想等待而不执行任何代码：

import time #Put this at the top of the script

time.sleep(10) #Put in the amount seconds

@boatofturtles:

重要免责声明：

这不是你在这个问题中所问问题的答案，所以请保留你选择的答案Remoltenreplied，因为这是对你所问问题的正确答案以及你提出问题的方式。

如果您不遵守上述免责声明，我将删除我的回答。您已收到警告:-D

免责声明说，经过一些挖掘和阅读与你正在做的这个游戏相关的另外两个问题（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 已被正确阻止）我想出了有一些我知道的代码确实可以按照您想要的方式工作（我在装有 Python 2.7 和 MacOs X 10.9.2 的 MacBook Air 上）该代码基于 this answer，正如我在评论中已经提到的那样one of your other questions，必须在 Mac 上工作（确实如此）。

我发布这个的原因（尽管根据 Stack Overflow 的条款和预期用途可能是错误的）是因为你让我想起了我写的第一个程序...... 15 年前。这是一个与您正在尝试做的非常相似的选择游戏（事实上，我什至没有调用 d*mn 函数 :-D ），它让我感到怀旧.你想做的是一个很好的练习，我不希望你气馁。编程很有趣，Python 是一门很好的语言。

请尝试理解我发布的代码中发生了什么（查看sys 和select 模块的文档，对于初学者）。是变得更好的唯一方法。谷歌搜索和阅读，阅读和练习。

另外，一个很棒的工具可以让人们告诉你如何提高你的编码技能，将你的代码发布到https://codereview.stackexchange.com/ 在那里创建一个帐户并询问你如何改进你的代码。

最后一件事：

当您在 Stack Overflow（或任何其他 stackexchange.com 网站）中发布问题时，请花一些时间准确地解释您的问题。 不起作用...它坏了...breakeEEEEeeen！告诉我一个修复方法！ 对任何人都没有帮助（好吧，不是你确实这样做了，但你必须认识到关于柯比游戏的第一个问题非常令人困惑）。

请记住，S.O.(StackOverflow) 是一个非常知名的网站，其答案多次出现在 Google 的第一批结果中。如果您正确地提出您的问题，您将获得更好的问题答案，并且您将帮助将来面临同样问题的其他人。

Stack Overflow 中有很多天才（是的，不是我，但我知道有！！）免费向所有人回答（我说的是 Wikipedia 上关于他们的文章的家伙，正确？）。所以。如果您使用得当，它是一个很好的资源（阅读this、this 并密切关注meta，了解 StackOverflow 网络中的网络礼仪）

好的，关于我的老前辈的故事已经讲完了，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 ""

1) Krazy hand.
2) Mister hand.
3) Ganondorf.
4) Yoshi.
