As Alex pointed out, not all Exceptions have an error number or code
associated with them.
Notice how much easier it is to help you, by the way, when you post a real
live sample of code. <wink>
In the case of the above, I would write that:
try:
server = smtplib.SMTP('XXXXXXX')
except Exception, e:
...
Then, interactively, just to figure this out, I'd do this:
print dir(e)
Hmm, there's an args attribute there. What's in it?
print e.args
Result:
(7, 'getaddrinfo failed')
So, in this caes, e.args is a tuple. 7 might be what you're looking for.
But I haven't looked into the smtplib module to see whether it is. But
that's the wonderful thing about open source--you can. <wink>
