构建用户列表,格式为:
[{‘user‘: ‘k1‘, ‘value‘: ‘v1‘},
{‘user‘: ‘k2‘, ‘value‘: ‘v2‘},
{‘user‘: ‘k3‘, ‘value‘: ‘v3‘}]
Q为停止录入,然后使用用户列表中的内容登陆,失败则重新输入.

lst = []
while 1:
    dic = {}
    a = input(‘用户名:‘)
    if a.upper() == "Q":
        break
    b = input(‘密码:‘)
    dic[‘user‘] = a
    dic[‘value‘] = b
    lst.append(dic)

print(lst)
while 1:
    username = input(‘请输入用户名:‘)
    password = input(‘请输入密码:‘)
    message = ‘登录失败!请重试!‘
    for i in lst:
        if i[‘user‘] == username and i[‘value‘] == password:
            message = ‘登陆成功!‘
            print(message)
            break
    if message == ‘登陆成功!‘:
        break
    print(message)
