Python's exception handling capability is powerful, providing users with accurate feedback on error messages. In Python, an exception is also an object that can be manipulated. All exceptions are members of the base class exception. All exceptions are inherited from the base class exception and are defined in the Exceptions module. Python automatically places all exception names in the built-in namespace, so the program does not have to import the exceptions module to use exceptions. Once thrown and not caught Systemexit exception, program execution terminates. If the interactive session encounters an Systemexit exception that is not caught, the session terminates.
Try
do Sth
Except Exception,ex:
Print Exception (ex)
