Create new instance of class with metaclass in python

Question

I would like to create dynamically a new instance of a class with a specific metaclass in python.

I've tried this :

type('A', (object,  metaclass=tmp, ), {})

but doesn't work :(

Does anybody know how I could achieve this?

A metaclass is typically a subclass of type, (or perhaps rarely a function taking name, bases, clsdict as arguments), so you should be able to use it like type. If tmp is your metaclass, then try:

tmp('A',(object,),{})
