There are maybe better base classes to use. Running the interpreter:
Python 2.6.5 (r265:79063, Apr 16 2010, 13:09:56)
[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import urllib2
>>> help (urllib2.HTTPError)
will show you
class HTTPError(URLError, urllib.addinfourl)
| Raised when HTTP error occurs, but also acts like non-error return
| Method resolution order:
So catching any of urllib2.HTTPError, urllib2.URLError, IOError,
EnvironmentError, or StandardError will detect the exception -- with
increasing levels of generality.
