특정 도시의 주간 기온을 횡단하는 Python 방법 분석

Y2J원래의: 2017-04-28 09:17:361492검색
이 글에서는 Python을 이용하여 특정 도시의 온도를 일주일 동안 횡단하는 구현 방법을 주로 소개합니다. 참고값이 아주 좋습니다. 편집자와 함께 살펴보겠습니다.
관심을 끌면서 특정 도시의 일기예보를 5일 이내에 작성하여 화씨로 변환했습니다.
도시를 쉽게 추가할 수 있도록 도시 이름을 목록에 작성하세요. 그리고 자세한 메모와 함께
import requests

#定义一个函数 避免代码重写多次。

 #print(r.text) 打印解码后的返回数据

 #print(type(data)) data 的数据类型是字典 所以可以按照字典操作（字典里的列表就按列表操作）

这是返回的一个json数据，可以通过json格式化工具查看会方便一些，通过json.loads其实都是字典列表的一些嵌套，而想要取的数据 在字典里"result"里， 而data[&#39;result&#39;] 又是一个字典，
