This example is for google, of course using pygoogle is easier in this case,
but this is a valid example for the general case :
>>>[207]: import urllib, urllib2
You need to trick the server with an imaginary User-Agent.
>>>[208]: def google_search(terms) :
return urllib2.urlopen(urllib2.Request("http://www.google.com/search?"; +
urllib.urlencode({'hl':'fr', 'q':terms}),
headers={'User-Agent':'MyNav 1.0
(compatible; MSIE 6.0; Linux'})
).read()
.....:
>>>[212]: res = google_search("python & co")
Now you got the whole html response, you'll have to parse it to recover datas,
a quick & dirty try on google response page :
>>>[213]: import re
>>>[214]: [ re.sub('<.+?>', '', e) for e in re.findall('<h2 class=r>.*?</h2>',
res) ]
