在没有try-catch块的情况下控制格式异常

var email = "example@example.com";
var emailPattern = /^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$/;

if (emailPattern.test(email)) {
  console.log("邮箱格式正确");
} else {
  console.log("邮箱格式错误");
}

import re

email = "example@example.com"
email_pattern = r'^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$'

if re.match(email_pattern, email):
    print("邮箱格式正确")
else:
    print("邮箱格式错误")
