不需要準備。

二．預覽1.啟動

啟動以后自動定位所在城市，展示定位城市的天氣。

2.添加城市

3.展示多個城市天氣

添加天氣之后能夠顯示多個城市天氣信息。

三．設計流程1.獲取城市天氣信息過程

用此流程圖展示定位城市信息到獲取城市天氣信息過程。

四．源代碼1.Weather_Tool-v1.0.py

本次使用Tkinter寫了一款天氣預報小工具，基本支持全國每個省市的天氣預報，支持歷史天氣（昨天）查看，雖然基本功能能夠實現，但是仍舊存在兩個小問題：1.添加超過兩個城市天氣后，具體城市信息會顯示在最新添加的Freame中。2.ip定位不準確。

本程序還有兩個特色：

1.支持更換主題。2.程序首次啟動加入了加載過渡。其他的彩蛋，您自己去發現吧！程序放在了藍奏云。思路、代碼方面有什么不足歡迎各位大佬指正、批評！

以上就是python制作的天氣預報小工具(gui界面)的詳細內容，更多關于python 天氣預報工具的資料請關注好吧啦網其它相關文章！
