用python中字符串中的另一个单词替换单词 [英] replacing word with another word from the string in python

问题描述

我有一个字符串:y，我同意你的看法."

我有数组字典[(word_will_replace, [word_will_be_replaced])]:

[('yes', ['y', 'ya', 'ye']), ('you', ['u', 'yu'])]

我想将 'y' 替换为 'yes' 并将 'u' 替换为 'you'根据数组字典.

i want to replace 'y' with 'yes' and 'u' with 'you' according to the array dictionary.

所以我想要的结果:是的，我同意你的看法."

我想保留标点符号.

推荐答案

import re
s="y, i agree with u. yu."
l=[('yes', ['y', 'ya', 'ye']), ('you', ['u', 'yu'])] 
d={ k : "\\b(?:" + "|".join(v) + ")\\b" for k,v in l}
for k,r in d.items(): s = re.sub(r, k, s)  
print s

输出

yes, i agree with you. you.
