python - TypeError when retrieving Google indexes for keywords -


we found code via google. supposed give google indexes keywords. problem works while gives error:

./g1.py size hassize traceback (most recent call last):   file "./g1.py", line 22, in <module>     n2 = int(gsearch(args[0]+" "+args[1])['cursor']['estimatedresultcount']) typeerror: 'nonetype' object unsubscriptable

the code:

#!/usr/bin/env python  import math,sys import json import urllib  def gsearch(searchfor):   query = urllib.urlencode({'q': searchfor})   url = 'http://ajax.googleapis.com/ajax/services/search/web?v=1.0&%s' % query   search_response = urllib.urlopen(url)   search_results = search_response.read()   results = json.loads(search_results)   data = results['responsedata']   return data  args = sys.argv[1:] m = 45000000000 if len(args) != 2:         print "need 2 words arguments"         exit n0 = int(gsearch(args[0])['cursor']['estimatedresultcount']) n1 = int(gsearch(args[1])['cursor']['estimatedresultcount']) n2 = int(gsearch(args[0]+" "+args[1])['cursor']['estimatedresultcount'])

i ran code few times , found every once in while query returns object has data['responsedata'] = none. causing error reported. find out why case, output entire data object when data['responsedata'] = none, , found following:

{u'responsedata': none,  u'responsedetails': u'suspected terms of service abuse.                        please see http://code.google.com/apis/errors',  u'responsestatus': 403}

it appears of requests returning http 403 forbidden status codes, , result query not being fulfilled (and has no data). read the page on google's terms of service , see if can figure out why of requests may violating terms of service.
