Get Latitude and Longitude from EXIF using PIL

get_lat_lon_exif_pil.py

import PIL.Image

get_float = lambda x: float(x[0]) / float(x[1])
def convert_to_degrees(value):
    d = get_float(value[0])
    m = get_float(value[1])
    s = get_float(value[2])
    return d + (m / 60.0) + (s / 3600.0)

def get_lat_lon(info):
    try:
        gps_latitude = info[34853][2]
        gps_latitude_ref = info[34853][1]
        gps_longitude = info[34853][4]
        gps_longitude_ref = info[34853][3]
        lat = convert_to_degrees(gps_latitude)
        if gps_latitude_ref != "N":
            lat *= -1

        lon = convert_to_degrees(gps_longitude)
        if gps_longitude_ref != "E":
            lon *= -1
        return lat, lon
    except KeyError:
        return None

Hi,
what is 'info' in the argument?
Is it gps exif info?
