python查天⽓预报_Python编写⼀个天⽓预报查询系统 学了Python这么久 可以⽤它来做许多好玩的⼩程序哦! 这⾥给 ⼤家做了个查询天⽓预报的⼩程序! 可以查询未来⼏天的天⽓! 需要⼤家⾃⼰修改下代码即可!
⾸先我们需要建⽴⼀个字典dict ⽤来存放城市编码! 因为API接⼝是根据城市编码来查询的 ! 由于城市编码⽐较多 2600多⾏ 所有不在这⾥发了! 需要的可以⾃⾏百度去下载哦! {"time":"2018-10-12 08:00:56","cityInfo":{"city":"北京市","cityId":"101010100","parent":"北

返回的是⼀个json 我们⽤ requests_html库 get请求即可 这个库是⾃带json()的!
好了 废话不多说了 我们还是直接上代码吧! 如有不⾜的地⽅欢迎指出!还请⼤神勿喷!
from requests_html import HTMLSession
from city import city
session = HTMLSession()
