[Tutor] question regarding python exception handling

To be honest I've never quite worked this out either.
But it's what the language does so I don't lose sleep
about it.

Instead of

try:
  # some code
except anException:
  # some more code
finally:
  # tidy up now

Just do:

try:
  try:
    # some code
  except anException:
    # some more code
finally:
 # tidy up now.

For the cost of 4 extra characters and some whitespace I
can live with it! :-)

FWIW Delphi does exactly the same.
