我正在创建一个接受用户输入并返回故事的 madlibs 游戏。我使用 %s 来存储输入。当我收到此错误时，我将之前的帖子中的 %s 更改为 %%s 但错误仍然存​​在

print "What is your name?"
a = raw_input()
print "Hello", a, "Lets see if you like you can do MadLibs!"
print "HEAD KNIGHT OF NI: %s \n KNIGHTS OF NI : %s \n ARTHUR : Who are you ? \n HEAD KNIGHT : We are the %s who say. %s \n RANDOM : %s \n ARTHUR : No ! Not the %s who say %s \n Head Knight: The Same! \n Bedevere: Who are they? \n Head Knight: We are the keepers of the %s words : %%s %%s and %%s \n Random: %%s \n Arthur: Those who %s them seldom live to tell the tale. \n Head Knight: The %%s who say %%s demand a sacrifice \n Arthur: %s of %s we are but %s travellers who seek the % who lives beyong these woods \n Head Knight: %s \n Knights of Ni: %s \n Arthur: Ow Agh \n Head Knight: We shall say %s again to you if you don't appease us \n Arthur: Well what is it you want? \n Head Knight: We want a %%s \n Arthur: A what? \n Knights of Ni: %%s \n Arthur and Party: OWWW, AHHH \n Arthur: Please, No More! We will find you a %%s \n Head Knight: You must return here with a %%s or else, you will never pass through these woods alive. \n Arthur: O %%s of %%s you are %%s and %%s and we will return with a %%s. \n Head Knight: One that looks %%s \n Arthur: Of Course \n Head Knight: and not too %%s \n Arthur: Yes" % (raw_input("Nonsense Word"), raw_input("Nonsense Word "), raw_input("Occupation"),raw_input("Nonsense Word"),
                       raw_input("Nonsense Word"), raw_input("Occupation"), raw_input("Nonsense Word"), raw_input("Adjective"), raw_input("Nonsense Word"),

错误是 ValueError：索引 466 处不支持的格式字符 'w' (0x77)

您的字符串中有一个文字%字符；将其加倍以防止 Python 尝试将其解释为格式字符串：

"... very long string ... who seek the %% who lives beyong ..."

或者你可能错过了s那里：

"... very long string ... who seek the %s who lives beyong ..."

不过，您真的想研究三次引用您的字符串。Python 让您将"""其用作字符串分隔符，并在这样的文字字符串中保留换行符：

MADLIBS = """\
HEAD KNIGHT OF NI: %s 
 KNIGHTS OF NI : %s 
 ARTHUR : Who are you ? 
 HEAD KNIGHT : We are the %s who say. %s 
 RANDOM : %s 
 ARTHUR : No ! Not the %s who say %s 
 Head Knight: The Same! 
 Bedevere: Who are they? 
 Head Knight: We are the keepers of the %s words : %%s %%s and %%s 
 Random: %%s 
 Arthur: Those who %s them seldom live to tell the tale. 
 Head Knight: The %%s who say %%s demand a sacrifice 
 Arthur: %s of %s we are but %s travellers who seek the %% who lives beyong these woods 
 Head Knight: %s 
 Knights of Ni: %s 
 Arthur: Ow Agh 
 Head Knight: We shall say %s again to you if you don't appease us 
 Arthur: Well what is it you want? 
 Head Knight: We want a %%s 
 Arthur: A what? 
 Knights of Ni: %%s 
 Arthur and Party: OWWW, AHHH 
 Arthur: Please, No More! We will find you a %%s 
 Head Knight: You must return here with a %%s or else, you will never pass through these woods alive. 
 Arthur: O %%s of %%s you are %%s and %%s and we will return with a %%s. 
 Head Knight: One that looks %%s 
 Arthur: Of Course 
 Head Knight: and not too %%s 
 Arthur: Yes
"""

这样你就可以更清楚地知道你%的字符串中有几个可能需要修复的百分比标记。

我认为您实际上并不想要其中的任何 %%s 字符串。而且，如果像“ni”这样的词可以始终保持一致，那就更有意义了。所以，我用键控占位符重写了它：

print "What is your name?"
a = raw_input()
print "Hello", a, "Let's see if you can do MadLibs!"
categories = {  'ni':'Nonsense word','knights':'Occupation',
                'sacred':'Adjective','peng':'Nonsense word',
                'nee-wom':'Nonsense word','hear':'Verb',
                'simple':'Adjective','enchanter':'Occupation',
                'shrubbery':'Noun','just':'Adjective',
                'fair':'Adjective','nice':'Adjective',
                'expensive':'Adjective'}
input_words = {}
for key,description in categories.items():
    input_words[key] = raw_input('Enter a(n) '+description+': ')
print '''HEAD KNIGHT OF NI: %(ni)s 
 KNIGHTS OF NI : %(ni)s 
 ARTHUR : Who are you ? 
 HEAD KNIGHT : We are the %(knights)s who say. %(ni)s 
 RANDOM : %(ni)s 
 ARTHUR : No ! Not the %(knights)s who say %(ni)s 
 Head Knight: The Same! 
 Bedevere: Who are they? 
 Head Knight: We are the keepers of the %(sacred)s words : %(ni)s %(peng)s and %(nee-wom)s 
 Random: %(nee-wom)s 
 Arthur: Those who %(hear)s them seldom live to tell the tale. 
 Head Knight: The %(knights)s who say %(ni)s demand a sacrifice 
 Arthur: %(knights)s of %(ni)s we are but %(simple)s travellers who seek the %(enchanter)s who lives beyond these woods 
 Head Knight: %(ni)s 
 Knights of Ni: %(ni)s 
 Arthur: Ow Agh 
 Head Knight: We shall say %(ni)s again to you if you don't appease us 
 Arthur: Well what is it you want? 
 Head Knight: We want a %(shrubbery)s 
 Arthur: A what? 
 Knights of Ni: %(ni)s 
 Arthur and Party: OWWW, AHHH 
 Arthur: Please, No More! We will find you a %(shrubbery)s 
 Head Knight: You must return here with a %(shrubbery)s or else, you will never pass through these woods alive. 
 Arthur: O %(knights)s of %(ni)s you are %(just)s and %(fair)s and we will return with a %(shrubbery)s. 
 Head Knight: One that looks %(nice)s 
 Arthur: Of Course 
 Head Knight: and not too %(expensive)s 
 Arthur: Yes''' % input_words
