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