Exception Handling

[Sheldon]

Hi,
This is a non-trivial thing that you are trying to do. You can use some
of python's built-in exceptions, like RuntimeError or IOError and if so
then:
try:
   call C
except IOError, e:
    print e

But this will return and print only IOErrors if they occur.

You can define your own error handling using the function RAISE:
try:
  Call C
except:
  raise my_error.

A catch-all error is RuntimeError; try this first.
try:
 call C
except RuntimeError, r:
  print r

You can read up on it here:

Sheldon
