Pythonic way to reverse lon,lat coordinates in a GeoJSON response

I would like to reverse the order of the coordinates in this JSON response from (lat,lon) to (lon,lat):

service=wfs&version=1.1.0&request=GetFeature&typeNames=sb:Conservation_Zone_WGS84&outputFormat=application/json'
response = requests.get(url).json()   
print response

{u'crs': {u'properties': {u'code': u'4326'}, u'type': u'EPSG'},
 u'features': [{u'geometry': {u'coordinates': [[[[39.81487959537135,
        -74.09688169446223],
       [39.81488113835475, -74.09587338924456],
       [39.8143317590967, -74.09614209870023],
       [39.8137616151959, -74.09633047532941],
       [39.812950626580545, -74.09670529470912],
       [39.8120075697193, -74.09698124228382],
       [39.814255381955064, -74.0973277412355],
       [39.81487959537135, -74.09688169446223]]]],
    u'type': u'MultiPolygon'},
   u'geometry_name': u'the_geom',
   u'id': u'Conservation_Zone_WGS84.1',
   u'properties': {u'ID': 1,
    u'NAME': u'Sedge Island Marine Conservation Zone',
    u'OBJECTID': 1,
    u'SHAPE_AREA': 70259289.0821,
    u'SHAPE_LEN': 40592.8006466,
    u'WEB_LINK': u'http://www.state.nj.us/dep/fgw/sedge.htm'},
   u'type': u'Feature'}],
 u'type': u'FeatureCollection'}

I could pull this apart, brute force it, and stick it back together, but I'm wondering: what would be a good pythonic way to change the order while leaving the structure intact?

Solution using numpy that should work for any geojson. It will flip all 'coordinates'.

import json
import requests
import numpy as np


def flip_geojson_coordinates(geo):
    if isinstance(geo, dict):
        for k, v in geo.iteritems():
            if k == "coordinates":
                z = np.asarray(geo[k])
                f = z.flatten()
                geo[k] = np.dstack((f[1::2], f[::2])).reshape(z.shape).tolist()
            else:
                flip_geojson_coordinates(v)
    elif isinstance(geo, list):
        for k in geo:
            flip_geojson_coordinates(k)

service=wfs&version=1.1.0&request=GetFeature&typeNames=sb:Conservation_Zone_WGS84&outputFormat=application/json"
resp = requests.get(url)
gj = json.loads(resp.text)

print gj
flip_geojson_coordinates(gj)
print gj
