python-正则表达试-实践1

匹配html标签中的任意标签内数据

1. 匹配所有包含'oo'的单词

   import re
   text = "JGood is a handsome boy, he is cool, clever, and so on..."
   re.findall(r'\w*oo\w*', text) 

2. 匹配 html中title里面的内容

   原文：
   

import re
file = r'./202304.html'
f = open(file,'r',encoding='utf-8')
origin_content = f.read()
#r'<title>(.*)</title>'  效果一样
result = re.findall(r'<title>(.*?)</title>',origin_content)
print(result)
f.close()
