inside the except clause, sys.exc_info() returns information
about the current exception.  for details, see:
http://www.python.org/doc/current/lib/module-sys.html

to print the full exception traceback (like the interpreter does
if you don't catch the exception at all), use the traceback
module:

hope this helps!
