urllib processes the response code, and follows redirects etc.  If urllib gets a
response code that it cannot deal with, it raises an exception (which includes
the error code).

If you want to check the response code for any given resource, use httplib
(see Ian's reply).  If you're building a link checker of some kind, you might
prefer an asynchronous HTTP client (which lets you issue multiple requests
at once, and process the responses as they arrive):
