我当前正在用python创建一个基于文本的控制台程序，我想添加一个命令以使用邮政编码显示当前天气。我已经尝试过广泛搜索它，但似乎找不到任何好的方法。适用于我要尝试的解决方案都是使用我不熟悉的技术，该技术用于使用python制作实际的应用程序。当前没有UI，我是python的初学者，因此解决方案越易读和易懂，效果会更好。

有两种主要方法。
[第一个是使用请求和beautifulsoup4进行网络抓取。这可以从Google轻松完成，因为如果您搜索“天气{city-name}”，它将为您提供那里天气的摘要。
第二种方法是使用诸如openweathermap之类的api，对于它来说，geeksforgeeks tutorial的用法很不错：
