Start

 1import logging
 2logger = logging.getLogger(__name__)
 3
 4def fetch_data(url):
 5    print("start")
 6    response = requests.get(url)
 7    return response.json()
 8
 9def process_data(data):
10    print("debug")
11    cleaned = clean(data)
12    return cleaned
13
14def save_results(results):
15    print("yo")
16    with open('out.json', 'w') as f:
17        json.dump(results, f)
