I am working on tag recommendation and need to convert all words in quotes to a single phrase. For example

Here's one way, using re.sub and a callback:

这是一种方法，使用re.sub和回调：

>>> import re
>>> string = "'In Absence of Good Men'"
>>> re.sub("'(.*?)'", lambda x: x.group(1).replace(' ', ''), string)
'InAbsenceofGoodMen'

You can make this a bit more readable, by moving the lambda out into its own function:

通过将lambda移动到它自己的函数中，你可以使它更具可读性：

def foo(m):
    if m:
        return m.group(1).replace(' ', '')

string = "'In Absence of Good Men'"
new_string = re.sub("'(.*?)'", foo, string)

You can catch non-matches and handle errors better this way.

您可以通过这种方式捕获不匹配并处理错误。
