Python實現正則表達式匹配任意的郵箱

首先來個簡單的例子，利用Python實現匹配163郵箱的代碼：

 

 

#-*- coding:utf-8 -*-
__author__ = '楊鑫'
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!')

 

 

接着來一個匹配全部郵箱格式的代碼：

 

#-*- coding:utf-8 -*-
__author__ = '楊鑫'
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!')
