Is there a way beyond catching exceptions(HTTPError,URLError), to check if access to a url is permitted.

I have to constantly(every 30 secs) ping a url (using urllib2.open)(which might or might not be valid). And throwing and catching exceptions each time seems excessive. I couldn't find anything in the documentation.

有帮助吗?

There's nothing wrong with using try/except. That's the way to do such things in python.

it's easier to ask forgiveness than permission
