Classes are also instances, usually they are instances of the type 'type' (and even 'type' is an instance of itself): >>> class SuperClass(object): pass >>> SuperClass.__class__ <type 'type'> >>> type(SuperClass) <type 'type'> >>> type.__class__ <type 'type'> Old style classes don't have a class attribute, but you shouldn't be using old style classes anyway and so long as you use type(x) to access its class rather than accessing the __class__ attribute directly that doesn't particularly matter. -- Duncan Booth http://kupuguy.blogspot.com -- http://mail.python.org/mailman/listinfo/python-list
