正则表达式是用于处理字符串的一大帮手，我也只是对正则表达式进行了简单的入门，写了一个匹配电子邮箱的脚本。

re库涵盖了正则表达式的多种操作～

#!/usr/bin/python3#Filename: match_email_1.pyimport rere_email1 = re.compile(r'[0-9a-zA-Z.]+@[0-9a-zA-Z.]+?com')re_email2 = re.compile(r'<[a-zA-Z]+\s[a-zA-Z]+>\s[0-9a-zA-Z.]+@[0-9a-zA-Z.]+?org')email_address = input('Please enter your email address:')if re_email1.match(email_address):    print ('Yes, your email_address is valid')    print (email_address)elif re_email2.match(email_address):    print ('Yes, your email_address is valid')    print (email_address)else:    print ('sorry, your email address is invalid')
