Python in a Nutshell

Name

excepthook

Synopsis

excepthook(type,value,traceback)

When an exception is not caught by any handler, Python calls excepthook, passing it the exception class, exception object, and traceback object, as covered in Chapter 6. The default excepthook displays the error and traceback. You can rebind sys.excepthook to change what is displayed for uncaught exceptions (just before Python returns to the interactive loop or terminates). The original value is also available as sys.__excepthook__.
