员工登录系统0.1

在列表中存存有一下数据

data_list = ['dream|521|music-run-sport',
'opp|666|swim-listen-sleep',
'hope_nb|888|eat-code',
'lj_bob_nb|000|read-write'
]

每一个元素对应的分别是

用户名|密码|爱好

获取每一个元素并 做登陆校验

校验用户是否存在，三次密码重试机会,校验密码是数字且必须是三位以内

密码正确登陆成功打印下列指定格式

欢迎用户 username 登陆！您有以下爱好 爱好1&爱好2&爱好3

如果用户名中带有 _nb 则打印 欢迎Vip用户 username 登陆！您有以下爱好 爱好1&爱好2&爱好3

如果用户名以 lj 开头则打印 欢迎尊贵的辣鸡用户 username 登陆！您有以下爱好 爱好1&爱好2&爱好3

lj打印的时候只要后边的用户名，不要lj_

把数据装到用名字当key的字典里，方便查找

data_dict = {}
for data in data_list:
# hobby_data = ' & '.join(data.split('|')[2].split('-')) # 把爱好切分重新连接
hobby_data = data.split('|')[2].replace("-",' & ') # 把爱好切分的第二种方法
data_dict[data.split('|')[0]] = [data.split('|')[1],hobby_data,'visit'] #增加键值对到字典

print(data_dict)
