Python通过正则表达式检测是否电子邮件地址
下面是Python通过正则表达式匹配来验证是否是电子邮件地址：
# Python program to validate an Email
# import re module
# re module provides support
# for regular expressions
import re
# Make a regular expression
# for validating an Email
regex = '^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$'
# Define a function for
# for validating an Email
def check(email):
# pass the regualar expression
# and the string in search() method
if(re.search(regex,email)):
print("Valid Email")
else:
print("Invalid Email")
# Driver Code
if __name__ == '__main__' :
# Enter the email
email = "ankitrai326@gmail.com"
# calling run function
check(email)
email = "my.ownsite@ourearth.org"
check(email)
email = "ankitrai326.com"
check(email) re.search()，如果模式不匹配，返回None。
