使用正则表达式将引号添加到python语句中的单词列表中

Question

我有一个单词列表，比如：

["apple", "orange", "plum"]

我只想在字符串中为这些单词添加引号：

Rita has apple  ----> Rita has "apple"
Sita has "apple" and plum ----> Sita has "apple" and "plum"

如何使用正则表达式在python中实现这一点？你知道吗

Answer 1

不使用regex的解决方案：

txt = "Sita has apple and plum"
words = ["apple", "orange", "plum"]
txt = " ".join(["\""+w+"\"" if w in words else w for w in txt.split()])
print (txt)

txt = "Rita drinks apple flavored snapple?"
txt = " ".join(["\""+w+"\"" if w in words else w for w in txt.split()])
print (txt)
