背景：

有些客户希望影刀提供天气查询指令，方便他们做一些商业决策。

效果：

1.获取实现天气。

2.天气预报。

使用方式：

1.原封不动的粘贴我的python代码。

2.去和风天气注册一个api key。链接： https://dev.qweather.com/

3.傻瓜式填入你的key，和你想要查询的城市。就可以得到json数据啦。

补充：

对比过一些其他api，感觉和风天气对中国城市来说兼容比较友好，其他的api可能搜不到或搜不准，返回的信息也很全。免费版一天可以查询5000次，应该够用了。。

细节：

原来返回的是英文指标，为了方便大家查看，建了一个翻译映射。可以自动帮我们转化。

全部代码：
