如何搜索多个字符串的字符串，然后用其他字符串替换它们？ （Python）

Question

我有以下句子“该男子去了商店”，我想用“狗”替换任何带有“th”或“sh”的单词。结果应该是这样的：

dogse人去dogse dogsop

这是我的代码看起来像至今：

sentence = "the man went to the shop" 

to_be_replaced = ["th", "sh"] 
replaced_with = "dogs" 

for terms in to_be_replaced: 
    if terms in sentence: 
     new_sentence = sentence.replace(terms,replaced_with) 
     print new_sentence 

目前，这款打印：

dogse man went to dogse shop 
the man went to the dogsop 

余万t它只打印此：

dogse man went to dogse dogsop 

我会去做这件事吗？

Answer 1

你只需要从一开始就相同的字符串工作，坚持工作。你不需要你的new_sentence（除非你想保留第一个）。

此代码应工作：

sentence = "the man went to the shop" 

to_be_replaced = ["th", "sh"] 
replaced_with = "dogs" 

for terms in to_be_replaced: 
    if terms in sentence: 
     sentence = sentence.replace(terms,replaced_with) 
print sentence 

它应该打印：

dogse man went to dogse dogsop 

Answer 2

这应该工作：

s.replace("th", "dogs").replace("sh", "dogs") 

Answer 3

import re 

text = "the man went to the shop" 
repalceed = re.sub(r'sh|th', 'dogs', text) 
print(repalceed) 

出来：

dogse man went to dogse dogsop
