替换字符串中的单词，忽略引号并匹配整个单词

Question

我知道这个问题与此处的其他问题非常相似，但是我无法从任何解决方案中调整一个可行的答案。 道歉！

我希望替换字符串中的单词，忽略引号中的任何内容，并匹配整个单词。

晚上好，我叫汤米，我喜欢足球，“我”最喜欢的运动是足球。

例如，我想替换“ my”，但是我不想替换“ myfootball”中的“ my”或“ my”。

我要替换的单词将从列表中读取。

谢谢，

Answer 1

您可以使用re模块：

>>> import re
>>> s = 'good evening my name is Tommy, I like football and "my" favourite sports is myfootball'
>>> re.sub(r"\ my "," your ", s)
'good evening your name is Tommy, I like football and "my" favourite sports is myfootball'

或str.replace函数：

>>> s.replace(' my ',' your ')
'good evening your name is Tommy, I like football and "my" favourite sports is myfootball'

Answer 2

In [84]: re.sub('\s+"|"\s+'," ",s) # sub a " preceded by a space or a "  followed by a space
Ot[84]: 'good evening my name is Tommy"s, I like football and my favourite sports is myfootball.'


In [88]: re.sub(r'"(my)"', r'\1', s)
Out[88]: 'good evening my name is Tommy, I like football and my favourite sports is my football.'

In [89]: re.sub(r'"(\w+)"', r'\1', s)
