简单的验证码小实验

import random
import time


def v_code():
    while True:
        code_1 = random.randint(0, 9)
        code_2 = random.randint(0, 9)
        code_3 = random.randint(0, 9)
        code_4 = random.randint(0, 9)
        v_number = input('请输入验证码{}{}{}{}，或者输入exit退出'.format(
            code_1, code_2, code_3, code_4))
        if v_number == 'exit':
            break
        if v_number == '{}{}{}{}'.format(code_1, code_2, code_3, code_4):
            print('验证成功，开始登陆.........')
            time.sleep(1)
            print('登陆成功......')
            time.sleep(1)
            break
        else:
            print('输入有问题请重新输入')
            continue


if __name__ == "__main__":
    v_code()
