MongoDB query (python)

def get_closest_airports(lonlat, limit=10):

json structure is as following

{"city": "Goroka", "tz": "Pacific/Port_Moresby", "name": "Goroka", "dst": "U", "loc": {"type": "Point", "coordinates": [145.391881, -6.081689]}, "country": "Papua New Guinea", "iata/faa": "GKA", "altitude": 5282.0, "icao": "AYGA", "timezone": 10.0, "id": 1}
