Python 不支持的格式字符“w”

Question

我正在创建一个 madlibs 游戏，它接受用户输入并返回故事。我使用 %s 来存储输入。当我收到此错误时，我将之前帖子中的 %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"),

错误为 ValueError：索引 466 处不支持格式字符“w”(0x77)

Answer 1

%你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 ..."

或者也许你错过了那里s：

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

不过，您确实想研究一下对字符串进行三重引用。Python 允许您使用"""字符串分隔符，并且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
"""

这样您就可以更清楚地知道%字符串中有几个可能需要修复的双百分号。
