首先来个简单的例子，利用Python实现匹配163邮箱的代码：
- __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：
- __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):
- print(‘Email address is Right!‘)
- else:
- print(‘Please reset your right Email address!‘)
Python实现正则表达式匹配任意的邮箱
