Python in a Nutshell

Name

displayhook

Synopsis

displayhook(value)

In interactive sessions, the Python interpreter calls displayhook, passing it the result of each expression-statement entered. The default displayhook does nothing if value is None, otherwise it preserves and displays value:

if value is not None:
    __builtin__._ = value
    print repr(value)

You can rebind sys.displayhook in order to change interactive behavior. The original value is available as sys.__displayhook__.
