Creating new JSON in Python from subset of larger JSON

Question

I'm new to python and am trying to do the following in Google Cloud Functions

1) Call an API to return JSON weather data

2) Extract relevant pieces of the returned data and create a new simple JSON

3) Publish JSON to BigQuery table

import requests
import json
from requests.auth import HTTPBasicAuth

weatherString = requests.get('https://twcservice.mybluemix.net/api/weather/v1/geocode/33.40/-83.42/observations.json?language=en-US&units=e', auth=HTTPBasicAuth('user','pass')

data=weatherString.json()

print("Hum",data['observation']['rh'])
print("Pressure",data['observation']['pressure'])
print("DewPt",data['observation']['dewPt'])
print("Temp",data['observation']['temp'])

This works to print the values from the keys but what I'm trying to do is create a new JSON object using these pairs. Any help greatly appreciated!

Answer 1

There's no such thing as a "JSON object" in Python -- what you're trying to create is a dict:

result = {
    "Hum": data['observation']['rh'],
    "Pressure": data['observation']['pressure'],
    "DewPt": data['observation']['dewPt'],
    "Temp": data['observation']['temp'],
}

This can then be serialized to a JSON string as follows:

json.dumps(result)
