1. Introduction to the match() method Before we start working on some coding examples that demonstrate the usage of the regex match() method you should understand what it is. The regex match() method is one of the re module’s methods that is used to search for a pattern at the beggin...
Here, we usedre.match()function to searchpatternwithin thetest_string. The method returns a match object if the search is successful. If not, it returnsNone. There are other several functions defined in theremodule to work with RegEx. Before we explore that, let's learn about regular express...

In this tutorial, you'll learn how to remove or replace a string or substring. You'll go from the basic string method .replace() all the way up to a multi-layer regex pattern using the sub() function from Python's re module.

正则表达式(英语:Regular Expression,在代码中常简写为regex、regexp或RE),又称正规表示式、正规表示法、正规表达式、规则表达式、常规表示法,是计算机科学的一个概念。正则表达式使用单个字符串来描述、匹配一系列匹配某个句法规则的字符串。在很多文本编辑器里,正则表达式通常被用来检索、替换那些匹配某个模式的文本。
