Adding location to Twitter sentiment analysis

I am trying to build a twitter sentiment analysis tool and want to add a geolocation - that looks for tweets within 10 miles of NYC. How do I do this? I I tried to add the location to the end of the url but it did not work.

Here is the code that I have so far:

import oauth2 as oauth
import urllib2 as urllib

# See assignment1.html instructions or README for how to get these credentials

api_key = ''
api_secret = ''
access_token_key = '
access_token_secret = ''

_debug = 0

oauth_token    = oauth.Token(key=access_token_key, secret=access_token_secret)
oauth_consumer = oauth.Consumer(key=api_key, secret=api_secret)

signature_method_hmac_sha1 = oauth.SignatureMethod_HMAC_SHA1()

http_method = "GET"


http_handler  = urllib.HTTPHandler(debuglevel=_debug)
https_handler = urllib.HTTPSHandler(debuglevel=_debug)

'''
Construct, sign, and open a twitter request
using the hard-coded credentials above.
'''
def twitterreq(url, method, parameters):
  req = oauth.Request.from_consumer_and_token(oauth_consumer,
                                             token=oauth_token,
                                             http_method=http_method,
                                             http_url=url, 
                                             parameters=parameters)

  req.sign_request(signature_method_hmac_sha1, oauth_consumer, oauth_token)

  headers = req.to_header()

  if http_method == "POST":
    encoded_post_data = req.to_postdata()
  else:
    encoded_post_data = None
    url = req.to_url()

  opener = urllib.OpenerDirector()
  opener.add_handler(http_handler)
  opener.add_handler(https_handler)

  response = opener.open(url, encoded_post_data)

  return response

def fetchsamples():

  url = "https://stream.twitter.com/1.1/statuses/filter.json?
  track=money&locations"
  parameters = []
  response = twitterreq(url, "GET", parameters)
  for line in response:
    print(line.strip())

if __name__ == '__main__':
  fetchsamples()

Here is the API doc: https://developer.twitter.com/en/docs/tweets/filter-realtime/api-reference/post-statuses-filter.html

statuses/filter uses POST, not GET.

For tweets around NYC use "locations=-74,40,-73,41". (You will need to expand this bounding box to make it 10 miles around NYC.) However, when used with track the two filters are OR'ed. In other words, you will get tweets that match either your locations filter or your track filter. You wont get only the tweets that match both filters.

EDIT

url = "https://stream.twitter.com/1.1/statuses/filter.json?track=money&locations=-74,40,-73,41"
parameters = []
response = twitterreq(url, "POST", parameters)
