You're of course right. Exceptions are mainly a way of handling 
'exceptional' conditions without cluttering the source code with error 
code checking. The canonical use case is:

try:
   some_call_that_may_raise(args)
except SomeException, e:
   try_to_solve_the_problem()

The nice thing with exceptions (compared to 'manual' error handling) is 
that you can choose where you want to handle the problem without having 
to pass back error code/error message all along the call stack...
