import urllib
import urllib2
import json
params = {'address': 'three pagodas,Dali,Yunnan,China','sensor': 'false'}
url = 'http://maps.googleapis.com/maps/api/geocode/json?' + urllib.urlencode(params)
rawreply = urllib2.urlopen(url).read()
result = json.loads(rawreply)
print json.dumps([(s['formatted_address'],s['geometry']) for s in result['results'], indent=2)
#源代码结束
下面是运行结果
