如何在python中将天气信息打印到控制台

Question

我目前正在 python 中创建一个基于文本的控制台程序，我想添加一个命令来使用邮政编码显示当前天气。我已经尝试过广泛使用谷歌搜索，但似乎找不到任何好的东西。适用于我正在尝试做的事情的解决方案都是使用我不熟悉的技术，这些技术用于使用 python 制作实际的应用程序。目前没有 UI，我是 python 的初学者，所以解决方案的可读性和易于理解性越好。

有两种主要方法可以做到这一点。

第一个是webscrape，使用requests和beautifulsoup4。这可以通过 google 轻松完成，因为如果您搜索“天气 {city-name}”，它会为您提供那里的天气摘要。

第二种是使用openweathermap之类的api，上面有个很棒的geeksforgeeks tutorial：
