在 Python 中替换字符串的一部分?

问题描述

我使用正则表达式从网页中获取一个字符串，该字符串的一部分可能包含我想用其他内容替换的内容.怎么可能做到这一点?我的代码是这样的，例如:

I used regular expressions to get a string from a web page and part of the string may contain something I would like to replace with something else. How would it be possible to do this? My code is this, for example:

stuff = "Big and small"
if stuff.find(" and ") == -1:
    # make stuff "Big/small"
else:
    stuff = stuff

推荐答案

>>> stuff = "Big and small"
>>> stuff.replace(" and ","/")
'Big/small'
