Required File

Download the city data and put it at any directory you want. Remember to set the path up when you initiate an instance.

Example

from Cities import cities_retriever
cr = cities_retriever.CitiesRetriever("Sources/dict_1.json")
cities = cr.retrieve_cities(-124.71, -77.21, 25.24, 44.75, 50) # starting longitude, ending longitude, starting latitude, ending latitude, the number of the cities 
print(json.dumps(cities, indent=2))

Note

it might take you a little time(13s for loading the dict) when you first invoke the retrieve method. But the loading process only occurs when you initiate an instance. The retrieving process is still stay around 0.001s ~ 0.01s(it depends on how many cities you want). The mainly time-consuming part in retrieving is a sorting part. You might wanna load it beforehand instead of loading it when you wanna use it.
