This module provides regular expression matching operations similar to Perl l. Unicode strings also apply.
The regular expression uses the Backslash "\" to represent a special form or as an escape character, which conflicts with the Python syntax. Therefore, python uses "\\\\" to represent "\" in a regular expression, because if a regular expression matches "\", it must be escaped "\\", in the P

Regular Expressions in python (re module) and python Regular Expressions
I. Introduction
Regular Expressions are a small and highly specialized programming language. In python, programmers can directly call the re module to implement regular expression matching. The regular expression mode is compiled into a series of bytecode and then executed by the matching engine written in C.
Ii. Meanings of common cha
This article introduces the re module of the Python standard library.
The re module provides a series of powerful regular expression tools that allow you to quickly check whether a given string matches a given pattern (match function ), or include this mode (search function ). Regular expressions are strings written in a compact (and mysterious) syntax.1. common methods

Descriptio
Today I learned about regular expressions in Python. I have not explained much about the regular expression syntax. I have learned a lot on the Internet. This section describes the re. match function, a common regular expression processing function in Python.
Re. match tries to match a pattern from the beginning of the string. for example, the following example matches the first word.
The code is as follow
applicable to programming languages such as Python and Perl.MetacharactersNote:
Re module
In Python, we can use the built-in re module to use regular expressions.
Note that regular expressions use\Escape special characters. for example, to match the string 'Python. org ', we need to use a regular expression.'python\.org'And Python strings also use\Therefore, the above regular expression should be written i

Re --- Python Regular Expression Module
Re is the most common Regular Expression module in Python. Common methods include compile, match, findall, finditer, search, split, and sub.
When some character strings are not easy to use, you can use the re module to conveniently perform operations such as search and replacement.

Now, you can try to match the different strings with the [a-z]+] of the RE. An empty string will not match at all, because the + means "one or

Regular expressions are a small and highly specialized programming language. they are not unique in python and are a basic and important part of many programming languages. In python, the re module is mainly used for implementation.
The regular expression mode is compiled into a series of bytecode and the
