- exception BaseException
The base class for all built-in exceptions. It is not meant to be directly inherited by user-defined classes (for that use Exception). If str() or unicode() is called on an instance of this class, the representation of the argument(s) to the instance are returned or the empty string when there were no arguments. All arguments are stored in args as a tuple.
New in version 2.5.
- exception Exception
All built-in, non-system-exiting exceptions are derived from this class. All user-defined exceptions should also be derived from this class.
Changed in version 2.5: Changed to inherit from BaseException.
