The very same thing. Why should it have a different meaning ?
For the record :
- 'object' is the base class for 'new-style' classes - that is, the
'new' (hem) object model that came with Python 2.2 (released december
2001 - so it's not that 'new'). The old one - known as 'classic classes'
has been kept so far for backward compat only, and will finally
disappear with Python 3.x.
- 'type' is the base metaclass. Python's classes being objects, they
have to be instances of a class - known as the metaclass. To avoid
metametaclasses, metametametaclasses etc ad infinitum, 'type' is an
instance of itself. And FWIW, a subclass of 'object', which is itself an
instance of 'type' (usually, brains start melting here...)
You'll find more informations (and hopefully clearer explanations) here:
and of course in the FineManual(tm):
