Question

我想在另一个列表中的索引列表中插入一个标点符号到句子中：

for x in range(len(final1)):
    final1.insert(punc_num[x], punct[x])- WHY WONT THIS WORK?

非常感谢任何帮助： - ）

整个代码：

f = open("file.txt","r") 
sentence= f.read()
print (sentence)

punctuations = ("'", "!", "(", ")", "-", "[", "]", "{", "}", ";", ":", '"', "<", ">", ".", "/", "?", "@", "#", "$", "%", "^", "&", "*", "_", "~", ",")

punc_num=[]

for x in sentence:
    if x in punctuations:
        punc_num.append(sentence.index(x))

print(punc_num)


punct=[]

for x in sentence:
    if x in punctuations:
        punct.append(x)

print(punct)





no_punct= ""

for y in sentence:
    if y not in punctuations:
        no_punct = no_punct + y

print (no_punct)





no_punct=no_punct.split()

final= (" ".join(sorted(set(no_punct), key=no_punct.index)))
print(final)
storing=[]

for x in no_punct:

    storing.append (no_punct.index(x))

print (storing)


final1= (" ".join(sorted(set(no_punct), key=no_punct.index)))
print(final1)




for x in range(len(final1)):
    final1.insert(punc_num[x], punct[x])

Answer 1

首先，当您使用final1.insert()时，final1是一个字符串，而不是一个列表。您可以通过执行以下操作来更新它：

final1_list = []
for x in range(len(punc_num)):
    final1_list.insert(punc_num[x], punct[x])
final1 = "".join(final1_list)

其次，在定义punc_num时，使用list.index()方法。由于list.index()将始终返回其参数的第一个次出现，因此任何给定的标点符号将始终具有相同的索引，无论它在字符串中出现的位置是多少。您可以将该循环更改为：

punc_num=[]
for x in sentence:
    if x in punctuations:
        index = 0
        while index + sentence[index:].index(x) in punc_num:
            index += sentence[index:].index(x) + 1
        punc_num.append(index + sentence[index:].index(x))

您的整个程序应如下所示：

f = open("file.txt","r")
sentence = f.read()
print (sentence)

punctuations = ("'", "!", "(", ")", "-", "[", "]", "{", "}", ";", ":", '"', "<", ">", ".", "/", "?", "@", "#", "$", "%", "^", "&", "*", "_", "~", ",")

punc_num=[]

for x in sentence:
    if x in punctuations:
        index = 0
        while index + sentence[index:].index(x) in punc_num:
            index += sentence[index:].index(x) + 1
        punc_num.append(index + sentence[index:].index(x))

print(punc_num)


punct=[]

for x in sentence:
    if x in punctuations:
        punct.append(x)

print(punct)





no_punct= ""

for y in sentence:
    if y not in punctuations:
        no_punct = no_punct + y

print (no_punct)



no_punct=no_punct.split()

final= (" ".join(sorted(set(no_punct), key=no_punct.index)))
print(final)
storing=[]

for x in no_punct:

    storing.append (no_punct.index(x))

print (storing)


final1= (" ".join(sorted(set(no_punct), key=no_punct.index)))
print(final1)




final1_list = list(final1)
for x in range(len(punc_num)):
    final1_list.insert(punc_num[x], punct[x])
final1 = "".join(final1_list)
