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]
正则表达式任意内容1. #-*- coding:utf-8 -*-
2. __author__ = '杨鑫'
3. import re
4. text = input("Please input your Email address:\n"):
5. if re.match(r'[0-9a-zA-Z_]{0,19}@163',text):
6.    print('Email address is Right!')
7. else:
8.    print('Please reset your right Email address!')
接着来⼀个匹配所有邮箱格式的代码:
[python]
1. #-*- coding:utf-8 -*-
2. __author__ = '杨鑫'
3. import re
4. text = input("Please input your Email address:\n")
5. if re.match(r'^[0-9a-zA-Z_]{0,19}@[0-9a-zA-Z]{1,13}\.[com,cn,net]{1,3}$',text):
6. #if re.match(r'[0-9a-zA-Z_]{0,19}@163',text):
7.    print('Email address is Right!')
8. else:
9.    print('Please reset your right Email address!')
