1项目目的与意义
1.1项目背景说明
通过爬取天气网站的数据以实现特定地区特定时间的天气 预报，要求界面用户输入需要预报的地区位置信息和需要预报的时间信息。
要求图形界面实现。
1.2项目目的与意义
可以获取全国各地各级城市的天气预报
2 软件开发环境与技术说明
2.1软件开发环境
Python 3.12
2.2软件开发技术描述
天气预报系统可以分为以下功能模块：
用户界面模块：
显示天气信息的表格；
提供输入框用于用户输入城市名称；
提供按钮触发获取天气信息的操作。
数据获取模块：
调用高德 API 请求城市天气数据。
数据处理模块：
从 API 返回的数据中提取并解析出需要的天气信息。
数据展示模块：
将获取的天气信息展示在用户界面的表格中。
3系统分析与设计
3.1项目需求分析说明
提供一个输入框，让用户输入要查询天气的城市名称。
提供一个按钮，用户点击后系统可以获取并显示该城市未来几天的天气信息。
显示天气信息的界面要清晰易读
3.2系统设计方案
- 前端界面使用Tkinter库来构建，定制样式以美化界面，提高用户体验。
- 后端通过调用高德API来获取城市天气信息，可以选择合适的第三方天气API服务。
- 数据库可以选择使用轻量级的SQLite数据库，存储城市信息和天气信息等数据。
- 可以考虑使用Python的Requests库来处理HTTP请求，获取API返回的JSON数据，并解析成Python数据结构用于显示在界面上。
- 在系统设计中考虑错误处理和异常情况，例如用户输入错误的城市名称或API请求失败时如何处理。
