GET

import requests
import json

def get_json():
    url = 'http://myurl.com/api.json')
    r = requests.request("GET", url)
    return(r.json())

if __name__ == '__main__':
    data = get_json()
    print(data)

POST

import requests
import json

def json_post():
    payload = {
        "data01": "hello",
        "data02": "world",
    }
    url = 'http://myurl.com/api/')
    r = requests.post(url, data=json.dumps(payload))
    print(r.status_code)
