Hello,
I use json for output instead of cvs, and it works. Also I convert the
lattitude and longitude into float.
enjoy
def get_lat_long(location):
key = settings.GOOGLE_API_KEY
output = "json"
location = urllib.quote_plus(location)
request =
"http://maps.google.com/maps/geo?q=%s&output=%s&key=%s
<http://maps.google.com/maps/geo?q=%s&output=%s&key=%s>" % (location,
output, key)
data = urllib.urlopen(request).read()
dlist = simplejson.loads(data)
if dlist['Status']['code'] == 200:
lat = float(dlist['Placemark'][0]['Point']['coordinates'][0])
long = float(dlist['Placemark'][0]['Point']['coordinates'][1])
return (lat, long)
else
return ''
