Python – API.reverse_geocode() in Tweepy

Twitter is a popular social network where users share messages called tweets. Twitter allows us to mine the data of any user using Twitter API or Tweepy. The data will be tweets extracted from the user. The first thing to do is get the consumer key, consumer secret, access key and access secret from twitter developer available easily for each user. 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.

Syntax : API.reverse_geocode(lat, long, accuracy, granularity, max_results)

Parameters :

• lat : latitude of the location.
• long : longitude of the location.
• accuracy : Specify the “region” in which to search.
• granularity : Assumed to be neighborhood by default, can also be city..
• max_results : maximum number of results to fetch.

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 = 28
long = 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

Example 2 : Exception is raised when giving invalid coordinates.

# invalid coordinates
lat = 200
long = 123

# fetching the locations
locations = api.reverse_geocode(lat, long)
