These keys will help the API for authentication.
API.reverse_geocode()
The reverse_geocode() method of the API class in Tweepy module is used to fetches the nearby locations for the provided coordinates.

Example 1 :
# import the module import tweepy # assign the values accordingly consumer_key = "" consumer_secret = "" access_token = "" access_token_secret = "" # authorization of consumer key and consumer secret auth = tweepy.OAuthHandler(consumer_key, consumer_secret) # set access to user's access key and access secret auth.set_access_token(access_token, access_token_secret) # calling the api api = tweepy.API(auth) # the coordinates lat = 28long = 77 # fetching the locations locations = api.reverse_geocode(lat, long) print(str(len(locations)) + " location(s) is / are fetched.") print("\nThe location(s) is / are :") for location in locations: print(location.name) |
Output :
2 location(s) is/are fetched. The location(s) is/are : Haryana India
