一个简单的带有 Tkinter 和 Newsapi 的新闻应用
原文:https://www . geesforgeks . org/a-simple-news-app-with-tkinter-and-news API/
先决条件 : Tkinter
Tkinter 是一个非常著名的 python 库，用于为基于 windows 和 UNIX 的操作系统构建桌面应用程序。这里的想法是生成一个 python 代码，用 Tkinter 构建一个新闻应用程序。您可以很容易地从 newsapi.org 获得一个应用编程接口密钥。
方法
- 导入模块
- 创建带有标题的屏幕
- 添加标签
- 添加按钮
- 为要显示的新闻创建一个文本区。
- 将按钮绑定到功能，以便在被点击时，新闻显示在文本区域
