Why 'class spam(object)' instead of class spam(Object)' ?

Because it is an exception ?-)

Notice that all builtin types (list, dict, set, str, unicode, int, long, 
float, tuple, file, object, type, function, classmethod, staticmethod, 
property etc) are lower-case.

(snip interrogations about "object"'s type)

type(Eggs) is roughly equivalent to Eggs.__class__, ie it returns the 
class of the Eggs class object, IOW the metaclass. In Python, classes 
are objects, so they are themselves instances of a class - by default, 
for new-style classes, instances of the class 'type'. In case you 
wonder, class 'type' is an instance of itself.

Idem !-)
