浅谈 while 循环用法
count = 1 while count < 3 : userd = input('用户登录:') psd = input('密码:') if userd == 'chentianjia' and pad == 'chen123..': print('欢迎光临') pass else: print('用户账号或者密码错误') count = 1 + count
whiile count <3 是将自己包含 if语句循环三次
不归属的不受限制,无限循环,例如,count = 1+count
count = 1 while count < 3 : userd = input('用户登录:') psd = input('密码:') if userd == 'chentianjia' and pad == 'chen123..': print('欢迎光临') pass else: print('用户账号或者密码错误') count = 1 + count
