的Python - 插入可變（多於一個號碼列表）

Question

我想在另一個列表中的列表的片標點的索引處插入一個句子：

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

任何幫助麻煩理解： - ）

整個代碼：

所有的

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，當你使用final1.insert()，final1是一個字符串，而不是一個列表。你可以這樣做更新：

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

其次，當你定義punc_num，您使用list.index()方法。由於list.index()將始終返回第一個其參數的出現，所以任何給定的標點符號將始終具有相同的索引，而不管它出現在字符串中的位數有多少。您可以在迴路改成這樣：

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)) 

你的整個程序應該是這樣的：

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)
