Filtering information from . JSON

I have the following script:

import json
import requests


def clima_semana():

    requisicao = requests.get('http://api.openweathermap.org/data/2.5/forecast?q=Rio de Janeiro&appid=233183ebc19d6700af2a1192a9c4bf74')
    previsao = json.loads(requisicao.text)

    return previsao['list'][0]['weather'][0]['description']

This function consumes a 5-day, 3-in-3-hour weather forecast API, but I only need the days' time description, at one time only. Notice how I had to index to get to the result! And this is only the first day, the structure is monstrous (lists within dictionaries that contain more dictionaries, etc).

How do I make one get just the information I need? Is there any other technique to solve this problem? The running time has also become super slow.

    Who dictates the return of JSON is the API, if that endpoint is not serving you, maybe you can consume some other: https://openweathermap.org/api

    Don’t let the API key exposed the view is public and may make misuse of it.

Can you be more clear about what you need from this Json? Can it be any time of a certain day ? It has to be a specific time ?

You can encapsulate your logic in another function:

def GetDescricaoDoClima(dia, hora):
    return previsao['list'][dia]['weather'][hora]['description']

Day and time will be the position in the json lists. Good luck!
