[Tutor] question about try & except

Yes,

You can catch an error object along with the exception, as in:

try:
     fileo = open("nofile")
except IOError, e:
     print "Alas...", e

As you see, the error object has a string representation equal wo what 
normally the python interpreter prints...

 >>>
Alas... [Errno 2] No such file or directory: 'nofile'
 >>>


Hope it helps. It took me originally a long time to know this trick, as 
it's kinda buried in the docs.
