break,continue的区别

break 终止循环,

continue 跳出本次循环,进入下一次循环

username = 'Loker'
passwd   = '123456'

for i in range(3):
    user = input('请输入您的用户名:')
    password = input('请输入您的密码:')
    if user == username and password == passwd:
        print('welcome,%s'%user)
        break
    else:
        print('sorry.your username or password is false')
