python如何制作的天氣預報小工具

這篇文章主要介紹python如何制作的天氣預報小工具，文中介紹的非常詳細，具有一定的參考價值，感興趣的小伙伴們一定要看完！

一．準備工作

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

from tkinter import *
from tkinter import ttk
from PIL import Image,ImageTk
from tkinter import messagebox
from Weather_Spider import Weather_Get
from threading import Thread
import datetime
import time

'''
5-1
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**

python的數據類型有哪些?

python的數據類型：1. 數字類型，包括int（整型）、long（長整型）和float（浮點型）。2.字符串，分別是str類型和unicode類型。3.布爾型，Python布爾類型也是用于邏輯運算，有兩個值：True（真）和False（假）。4.列表，列表是Python中使用最頻繁的數據類型，集合中可以放任何數據類型。5. 元組，元組用”()”標識，內部元素用逗號隔開。6. 字典，字典是一種鍵值對的集合。7. 集合，集合是一個無序的、不重復的數據組合。
