It's also worth being aware of the StandardError exception. If you 
don't know which specific exception will be raised, then 
StandardError will catch all raised exceptions, rather than specific 
ones (AFAIK!).

try:
    x = string.atoi("duh")
except StandardError, problem:
    print problem

Best wishes,

Lindsay
