# make a basic Point class

          Point(5,6)]

# implement the function gmaps_img(points) that returns the google maps image
# for a map with the points passed in. A example valid response looks like
# this:
#
# http://maps.googleapis.com/maps/api/staticmap?size=380x263&sensor=false&markers=1,2&markers=3,4
#
# Note that you should be able to get the first and second part of an individual Point p with
# p.lat and p.lon, respectively, based on the above code. For example, points[0].lat would 
# return 1, while points[2].lon would return 6.

GMAPS_URL = "http://maps.googleapis.com/maps/api/staticmap?size=380x263&sensor=false&"

def gmaps_img(points):
    markers = "&".join("markers=%s,%s" % (point.lat, point.lon) for point in points)
    return GMAPS_URL + markers
    ###Your code here
print gmaps_img(points)

If I define the namedtuple as 'Point', then pickle is happy:

Point = namedtuple('Point','x y')
pp = Point(1,2)
ppp = pickle.dumps(pp)
