试图用正则表达式在一组单词前后找到两个单词

Question

sentence = "I love the grand mother bag i bought . I love my sister's ring "

import re

regex = re.search('(\w+){2}the grand mother bag(\w+){2}', sentence)
print(regex.groups())

I should have extracted: I love and I bought.

Any idea where I went wrong?

Answer 1

Change your regex: \w does not match word but a character so you extract only 2 characters:

>>> re.search('(\w+\s+\w+)\s+the grand mother bag\s+(\w+\s+\w+)', sentence).groups()

('I love', 'i bought')
