Python re moduleIn Python, the re module provides regular expression matching operations. A pattern is a regular expression that defines the text we are searching for or manipulating. It consists of text literal

Python有关正则表达式的方法是在re模块内,所以使用正则表达式需要导入re模块。 import re 1. 本篇文章先介绍一下re模块中的几个函数: re.match() 这个方法和re.search()方法类似,但是也有点小差别的: re.match从字符串的开头开始匹配(也就是说待匹配字符在中间是匹配不到的),如果找到匹配项,则返回一个匹配对...
A regular expression (or RE) specifies a set of strings that matches it; the functions in this module let you check if a particular string matches a given regular expression. You may read ourPython regular expressiontutorial before solving the following exercises. ...
