A class is an object like any other. You can pass around references to classes like any other reference, and you can create them just as well: >>> def make_me_a_class(): ... class A(object): ... def f(self): ... print "I'm a class" ... return A ... >>> B = make_me_a_class() >>> c = B() >>> c.f() I'm a class >>> -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
