url - Python getting all links from a google search result page

Question

i want to create a script that returns all the urls found in a page a google for example , so i create this script : (using BeautifulSoup)

import urllib2
from BeautifulSoup import BeautifulSoup
page = urllib2.urlopen("https://www.google.dz/search?q=see")
soup = BeautifulSoup(page.read())
links = soup.findAll("a")
for link in links:
    print link["href"]

and it return this 403 forbidden result :

Traceback (most recent call last):
  File "C:Python27sqlsql.py", line 3, in <module>
    page = urllib2.urlopen("https://www.google.dz/search?q=see")
  File "C:Python27liburllib2.py", line 126, in urlopen
    return _opener.open(url, data, timeout)
  File "C:Python27liburllib2.py", line 400, in open
    response = meth(req, response)
  File "C:Python27liburllib2.py", line 513, in http_response
    'http', request, response, code, msg, hdrs)
  File "C:Python27liburllib2.py", line 438, in error
    return self._call_chain(*args)
  File "C:Python27liburllib2.py", line 372, in _call_chain
    result = func(*args)
  File "C:Python27liburllib2.py", line 521, in http_error_default
    raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)
urllib2.HTTPError: HTTP Error 403: Forbidden

any idea to avoid this error or another methode to get the urls from of the search result ?

Answer 1

No problem using requests

import requests
from BeautifulSoup import BeautifulSoup
page = requests.get("https://www.google.dz/search?q=see")
soup = BeautifulSoup(page.content)
links = soup.findAll("a")

Some of the links have links are like search%:http:// where the end of one joins another so we need to split then using re

import requests
from bs4 import BeautifulSoup
page = requests.get("https://www.google.dz/search?q=see")
soup = BeautifulSoup(page.content)
import re
links = soup.findAll("a")
for link in  soup.find_all("a",href=re.compile("(?<=/url?q=)(htt.*://.*)")):
    print re.split(":(?=http)",link["href"].replace("/url?q=",""))
