如何在字符串中搜索多个字符串，然后用其他字符串替换它们？ （蟒蛇）

Question

我有以下句子“男人去了商店”，我想用“狗”取代任何带有“th”或“sh”的单词。结果看起来应该是这样的：

狗人去了dogse dogop

这是我的代码到目前为止的样子：

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，这会打印：

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

我希望它只打印这个：

dogse man went to dogse dogsop

我会这样做吗？

Answer 1

这应该有效：

failedMessage

Answer 2

您只需从头开始处理相同的字符串并继续处理它。你不需要你的new_sentence（除非你想保留第一个）。

此代码应该有效：

<h:inputTextarea rows="5" cols="70" value="#{ticketBean.ticket.descripcio}" >
</h:inputTextarea>

应该打印：

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

Answer 3

import re

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

出：

dogse man went to dogse dogsop
