Re: Difference between type and class

That would imply that I cannot create instances of a type, only of
a class that implements the type, wouldn't it?

But Python denotes 'int' as a type *and* I can instantiate it.

Now I start getting confused also ;-)

>>> a=5
>>> a.__class__
<type 'int'>
>>> a.__class__.__class__
<type 'type'>
>>> dir(a)
['__abs__', '__add__', '__and__', '__class__', '__cmp__', '__coerce__', '__delattr__', '__div__', '__divmod__', '__doc__', '__float__', '__floordiv__', '__getattribute__', '__getnewargs__', '__hash__', '__hex__', '__index__', '__init__', '__int__', '__invert__', '__long__', '__lshift__', '__mod__', '__mul__', '__neg__', '__new__', '__nonzero__', '__oct__', '__or__', '__pos__', '__pow__', '__radd__', '__rand__', '__rdiv__', '__rdivmod__', '__reduce__', '__reduce_ex__', '__repr__', '__rfloordiv__', '__rlshift__', '__rmod__', '__rmul__', '__ror__', '__rpow__', '__rrshift__', '__rshift__', '__rsub__', '__rtruediv__', '__rxor__', '__setattr__', '__str__', '__sub__', '__truediv__', '__xor__']

I think in Python everything is implemented as a class which makes sense. AFAIK you can implement a certain interface in a custom class and it behaves like, for example, a builtin integer. But I guess one of the gurus can clarify this matter with an appropriate URL ;-)
