Python 地下天气预报
我正在尝试按天分离天气api的代码。目前,我可以获取forecastday的数组,但无法获取fcttext和title的每个数组。以下是我迄今为止用python编写的代码和我想要提取的数据:Python 地下天气预报,python,json,api,parsing,web-scraping,Python,Json,Api,Parsing,Web Scraping,我正在尝试按天分离天气api的代码。目前,我可以获取forecastday的数组,但无法获取fcttext和title的每个数组。以下是我迄今为止用python编写的代码和我想要提取的数据: import requests from pprint import pprint import json r = requests.get("http://api.wunderground.com/api/id/forecast10day/q/CA/San_Francisco.json") data =

"pop":"60"
}
data['forecast']['txt\u forecast']['forecastday']
中的值是字典列表。因此,您需要在该列表上循环以从中取出项目
for forecastday in data['forecast']['txt_forecast']['forecastday']:
print(forecastday['title'])
print(forecastday['fcttext'])
产生:
Thursday
Cloudy early with peeks of sunshine expected late. High 54F. Winds W at 10 to 20 mph.

谢谢您!工作完美。
