Example of Reverse Geocoding in python with Google Maps api

geo.py

import requests


def example():
    # grab some lat/long coords from wherever. For this example,
    # I just opened a javascript console in the browser and ran:
    #
    # navigator.geolocation.getCurrentPosition(function(p) {
    #   console.log(p);
    # })
    #
    latitude = 35.1330343
    longitude = -90.0625056

    # Did the geocoding request comes from a device with a
    # location sensor? Must be either true or false.
    sensor = 'true'

    # Hit Google's reverse geocoder directly
    # NOTE: I *think* their terms state that you're supposed to
    # use google maps if you use their api for anything.
    base = "http://maps.googleapis.com/maps/api/geocode/json?"
    params = "latlng={lat},{lon}&sensor={sen}".format(
        lat=latitude,
        lon=longitude,
        sen=sensor
    )
    url = "{base}{params}".format(base=base, params=params)
    response = requests.get(url)
    return response.json['results'][0]['formatted_address']

How to print the results in my console?

return response.json()['results'][0]['formatted_address']

I changed the return statement and got this error:

IndexError                                Traceback (most recent call last)
<ipython-input-3-48cbd428257a> in <module>()
     29     response = requests.get(url)
     30     return response.json()['results'][0]['formatted_address']
---> 31 example()

IndexError: list index out of range

I am really looking for how to write python code that will read a .csv file that just contains latitudes and longitudes for locations in California. I would like for it to read in each row and convert the lat/long to a county in California. This seems like it would be much more simple than these examples however I don't know how to do this. Also, would I use Python 2.7 for GIS python apps?

Thanks very much for any help someone could provide!
