第17章

17.1 使用Web API

        Web API作为网站的一部分，用于与使用具体URL请求特定信息的程序交互，这种请求称为API调用。

        17.1.1 Git 和 GitHub

                Git：分布式版本控制系统，帮助人们管理为项目所做的工作，避免一个人所做的影响其他人所做的修改（类似于共享文档）。在项目实现新功能时，Git跟踪你对每个文件所做的修改，确认代码可行后，提交上线项目新功能。如果犯错可撤回，可以返回之前任何可行状态。

                GitHub：让程序员可以协助开发项目的网站。

        17.1.2 使用API调用请求数据             

浏览器地址栏输入：https://api.github.com/search/repositories?q=language:python&sort=stars

                显示结果：
