Python不支持的格式字符“w”

Question

我正在创建一个madlibs游戏，需要用户输入并返回故事。我使用％s来存储输入。当我得到这个错误，我改变了％s到每以前的职位，但错误%%的遗体

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异常：不支持的格式字符“W”（0x77）的指数466

Answer 1

你有字符串中的文字%;一倍，以防止Python从试图把它解释为一个格式字符串：

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

或者你上一个s错过了那里，而不是：

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

你真的想看看特里普尔，引用您的字符串虽然。 Python中让你用"""作为字符串分隔符，这样的文字串换行符被保留：

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 
""" 

这样你可以更加清楚地表明你有几个一倍，你的字符串%％的痕迹，可能需要修正。

我不认为你真的想要那里的任何%% s字符串。而且，如果“ni”这样的词可以始终保持一致，那么它就更有意义。所以，我用重点占位符重写了它：

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
