python制作的天气预报小工具(gui界面)

一．准备工作

不需要准备。

二．预览

1.启动

启动以后自动定位所在城市，展示定位城市的天气。

2.添加城市

3.展示多个城市天气

添加天气之后能够显示多个城市天气信息。

三．设计流程

1.获取城市天气信息过程

用此流程图展示定位城市信息到获取城市天气信息过程。

四．源代码

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

1.打开首页定位当前位置获取天气    (ip定位+jieba分词+城市号+城市天气) **5.11实现**
2.用户手动选择，查看当前所选城市天气 （toplevel+combobox） **已实现**
5-14
1.加入notepad，显示多个城市天气    （notebook frame）    **已实现**
2.频繁刷新检测（线程计时10秒）   **已实现**
3.用户选择主题    (menu.add_radiobutton())    **已实现**
4.一个窗口多个combobox，怎样处理选择事件	**已实现**
5-15
1.右击notebook frame标题出现“关闭”菜单	**已砍掉**
2.用户添加了城市后，label出现在了最后的frame中	**未实现**

五．总结

本次使用tkinter写了一款天气预报小工具，基本支持全国每个省市的天气预报，支持历史天气（昨天）查看，虽然基本功能能够实现，但是仍旧存在两个小问题：
1.添加超过两个城市天气后，具体城市信息会显示在最新添加的freame中。
2.ip定位不准确。

本程序还有两个特色：

1.支持更换主题。
2.程序首次启动加入了加载过渡。
其他的彩蛋，您自己去发现吧！
程序放在了蓝奏云。思路、代码方面有什么不足欢迎各位大佬指正、批评！

以上就是python制作的天气预报小工具(gui界面)的详细内容，更多关于python 天气预报工具的资料请关注www.887551.com其它相关文章！
