python基础1：对input的参数进行简单的条件判断

#注1：此处可将定义的值替换为表格读取的登录账号、密码
_username = 'test'
_password = 'test123'
#解注1：动态获取账号、密码
#如下为举例，待后续修正：
# _username = info[1]
# _password = info[2]

#此处显示出交互窗口：
username = input('username:')
password = input('password:')

#登录结果判断并回显
if _username == username and _password == password:
    print('welcome to {name} login...'.format(name=username))
else:
    print('invalid username or password!')
