problem with urllib

[venkat sanaka]

Hello everyone
I am happy that my code finally worked and got the expected result.i suppose
the problem is with python 3 becoz i wrote
the similar code with python 2.5 without explicitly mentioning the proxy and
it worked.It has taken the system's proxy settings as given in the
documentation.Thanks a lot for ur replies.
Final code:
>>>import urllib2
>>> opener = urllib2.build_opener()
>>> opener.add_header = [('User-agent', 'Mozilla')]
>>>res=opener.open('http://www.google.com')
>>> print res.read()
