Python实现正则表达式匹配任意的邮箱

首先来个简单的例子，利用Python实现匹配163邮箱的代码：

[python] view plain copy

print?

#-*- coding:utf-8 -*-

__author__ = '杨鑫'

import re

text = input("Please input your Email address：\n"):

if re.match(r'[0-9a-zA-Z_]{0,19}@163.com',text):

print('Email address is Right!')

else:

print('Please reset your right Email address!')



接着来一个匹配所有邮箱格式的代码：

[python] view plain copy

print?

#-*- coding:utf-8 -*-

__author__ = '杨鑫'

import re

text = input("Please input your Email address：\n")

if re.match(r'^[0-9a-zA-Z_]{0,19}@[0-9a-zA-Z]{1,13}\.[com,cn,net]{1,3}$',text):

#if re.match(r'[0-9a-zA-Z_]{0,19}@163.com',text):

print('Email address is Right!')

else:

print('Please reset your right Email address!')
