1.打開首頁定位當前位置獲取天氣 (ip定位+jieba分詞+城市號+城市天氣) **5.11實現**
2.用戶手動選擇,查看當前所選城市天氣 (Toplevel+Combobox) **已實現**
5-14
1.加入notepad,顯示多個城市天氣 (notebook Frame) **已實現**
2.頻繁刷新檢測(線程計時10秒) **已實現**
3.用戶選擇主題 (Menu.add_radiobutton()) **已實現**
4.一個窗口多個Combobox,怎樣處理選擇事件 **已實現**
5-15
1.右擊notebook frame標題出現“關閉”菜單 **已砍掉**
2.用戶添加了城市后,label出現在了最后的Frame中 **未實現**
