經理管理一個餐廳，推出每天都有特色菜的營銷模式。他想根據一周中的每一天有一種特色菜。
客人想知道當天的特色菜是什么。另外再添加一個介紹頁面。bios路徑下，顯示餐廳主人，廚師，服務生的簡介。
python文件同級目錄下創建templates，把所有模板都保存在這里。
廚師將當前特色菜品存儲在一個json文件中。
{"monday":"烘肉卷配辣椒醬",
"tuesday":"Hamburger",
"wednesday":"扣肉飯",
"thursday":"泡菜鍋",
"friday":"漢堡",
"saturday":"Pizza",
"sunday":"肥牛燒"}
把餐廳主任，廚師，服務生的介紹也保存在一個json文件中。
{"owner":"餐廳的主人",
"cooker":"帥帥的廚師",
"server":"美麗可愛漂亮大方的服務生"}
