Question

我正在努力学习python课程，我不得不使用python创建自己的小故事。我确实做到了，我花了很多时间来解决它的许多问题，但是有一个变量导致了很多错误。

这是我的代码：

    $('#mySpinStrings', expiryControlsW).spinstrings({
        options: ['day', 'week', 'month'],
        value: 'week'
    });

我似乎在变量“fight_answer_y”方面遇到错误这是我得到的错误：

def party():
print "You are at a friend's house, and there you find three men who disrespect you.\
\nDo you fight them, insult back, or do you invite them for a drink?"
party_answer = raw_input()
while (party_answer != "fight") and (party_answer != "insult") and (party_answer != "drink"):
    print "Type either 'fight', 'insult', or 'drink'"
    party_answer = raw_input()  

if party_answer == "fight":
    fight()
elif party_answer == "insult":
    insult()
elif party_answer == "drink":
    drink()


def fight():
    print """You decide to fight the men.
After a while, the men start pleading for mercy.
Do you hit them more?"""
fight_answer = raw_input()
while (fight_answer != "yes") and (fight_answer != "no"):
    print "Type either 'yes' or 'no'"
    fight_answer = raw_input()

if fight_answer == "yes":
    print """Your friend sees you fighting and asks you why
Do you blame them, or do you take responsibility and apologize?"""
    fight_answer_y = raw_input()
    while (fight_answer_y != "blame them") and (fight_answer_y != "apologize"):
        print "Type either 'blame them' or 'apologize'"
        fight_answer_y = raw_input()

    if fight_answer_y == "blame them":
        print """Your friend is angry at you fighting at all, and does not believe \
that they started the fight. He kicks you out of the party."""
        exit(1)
    elif fight_answer_y == "apologize":
        print "Your friend forgives you, and asks you to drink with him."
        exit(2)

elif fight_answer == "no":
    print """The men take advantage of you forgiveness and start hitting you.
Fortunately, your friend arrives at this moment. He see them hitting you, \
and then kicks them out of the party."""
    exit(2)

def insult():
print """You insult them, and they challenge you to a fight.
Do you fight them or tell your friend?"""
insult_answer = raw_input()
while (insult_answer != "fight") and (insult_answer != "tell friend"):
    print "Type either 'fight' or 'tell friend'"
    insult_answer = raw_input()

if insult_answer == "fight":
    fight()
elif insult_answer == "tell friend":
    print """You decide to tell your friend.
He says he is happy you told him, and invites you for a drink
The men get kicked out"""
    exit(2)

def drink():
print """You tell them that you will buy drinks for them,\
and they rudely ask you why you are doing this.
Do you insult them or give them a polite response?"""
drink_answer = raw_input()
while (drink_answer != "insult") and (drink_answer != "polite response"):
    print "Type either 'insult' or 'polite response'"
    drink_answer = raw_input()

if drink_answer == "insult":
    insult()
elif drink_answer == "polite response":
    print "You politely respond to them, and they sit down with you and apologize."
    exit(2)

def exit(x):
if x == 1:
    print "You lost. Better luck next time!"
    again = raw_input("Do you want to try again?: ")
    while (again != "yes") and (again != "no"):
        print "Type either 'yes' or 'no'"
        again = raw_input("Do you want to try again?: ")

    if again == "yes":
        party()
    elif again == "no":
        quit()

elif x == 2:
    print "You won. Good job!"
    again = raw_input("Do you want to try again?: ")
    while (again != "yes") and (again != "no"):
        print "Type either 'yes' or 'no'"
        again = raw_input("Do you want to try again?: ")

    if again == "yes":
        party()
    elif again == "no":
        quit() 

party()

任何人都可以帮助解释这个，因为我是Python的新手。提前致谢

你的缩进是错误的。就我所知，这似乎有效。

def party():
    print "You are at a friend's house, and there you find three men who disrespect you.\
    \nDo you fight them, insult back, or do you invite them for a drink?"

    if party_answer == "fight":
        fight()
    elif party_answer == "insult":
        insult()
    elif party_answer == "drink":
        drink()

简短回答：始终将编辑器配置为将标签展开到四个空格，按PEP8，不要只显示标签为四个空格，因为它隐藏了混合标签和空格的问题。

说明：在your paste中，问题是elif和关联的块缩进得太浅，附加到外部if而不是内部if＆＃39;应该依附于。问题是因为您正在混合空格和制表符，if fight_answer_y == "blame them":缩进了两个制表符，而elif fight_answer_y == "apologize":缩进了八个空格。您可能正在使用一个将选项卡显示为四个空格的编辑器（Stack Overflow也会这样做），因此它们以相同的对齐方式显示，但Python 2始终将选项卡视为等效于八个空格，因此代码看起来如此像：

if fight_answer == "yes":
    print """Your friend sees you fighting and asks you why
Do you blame them, or do you take responsibility and apologize?"""
    fight_answer_y = raw_input()
    while (fight_answer_y != "blame them") and (fight_answer_y != "apologize"):
        print "Type either 'blame them' or 'apologize'"
        fight_answer_y = raw_input()

    if fight_answer_y == "blame them":
        print """Your friend is angry at you fighting at all, and does not believe \
that they started the fight. He kicks you out of the party."""
        exit(1)
    elif fight_answer_y == "apologize": # <-- ***LOOKS LIKE ATTACHED TO if fight_answer_y == "blame them":***
        print "Your friend forgives you, and asks you to drink with him."
        exit(2)

elif fight_answer == "no":
    print """The men take advantage of you forgiveness and start hitting you.

感谢您的编辑器显示标签，因为四个空格缩进被解释为：

if fight_answer == "yes":
    print """Your friend sees you fighting and asks you why
Do you blame them, or do you take responsibility and apologize?"""
    fight_answer_y = raw_input()
    while (fight_answer_y != "blame them") and (fight_answer_y != "apologize"):
        print "Type either 'blame them' or 'apologize'"
        fight_answer_y = raw_input()

    if fight_answer_y == "blame them":
        print """Your friend is angry at you fighting at all, and does not believe \
that they started the fight. He kicks you out of the party."""
        exit(1)
elif fight_answer_y == "apologize": # <-- ***ACTUALLY ATTACHED TO if fight_answer == "yes":***
    print "Your friend forgives you, and asks you to drink with him."
    exit(2)

elif fight_answer == "no":
    print """The men take advantage of you forgiveness and start hitting you.

感谢Python将相同的标签视为八个空格缩进。你运气不好，缩进似乎有效（大多数其他类似的失败意味着语法错误，或导致代码退出方法定义，因此失败是显而易见的）。在这种情况下，这意味着当fight_answer不是"yes"时，您尝试测试fight_answer_y == "apologize"，但fight_answer_y仅在fight_answer == "yes"中定义case，意思是fight_answer_y未定义。

如果您的编辑器配置为遵循PEP8（将标签展开到空格，使用四个空格缩进），则对齐问题就很明显了。如果您一直在使用Python 3，那么它对标签和空格的使用不一致的能力就会降低，而您的代码会报告TabError: inconsistent use of tabs and spaces in indentation的问题。但事实上，你的代码看起来很正确，并且运行错误。再次： 总是使用PEP8空格规则来避免这样的问题。那里的每个编辑器（除了记事本）都可以配置为将标签扩展到具有四个空格缩进的空格;做到这一点。

我的一个变量似乎不起作用，我找不到
