Hi Python users,

I have been using try...except statements in the situations where I can expect a certain type of errors might occur. 
But  sometimes I don't exactly know the possible error types, or sometimes I just can't "spell" the error types correctly. 
For example, 

try:
	response = urlopen(urljoin(uri1, uri2))
except urllib2.HTTPError:
	print "URL does not exist!"

Though "urllib2.HTTPError" is the error type reported by Python, Python doesn't recognize it as an error type name. 
I tried using "HTTPError" alone too, but that's not recognized either.

Does anyone know what error type I should put after the except statement? or even better: is there a way not to specify
the error types? Thank you.
