23 # type(name of the class,
24 #      tuple of the parent class (for inheritance, can be empty),
25 #      dictionary containing attributes names and values)
26 
27 cls_name = "Spam"
28 bases = (object,)
29 dct = {"__init__": __init__, 
30        "class_method": class_method, 
31        "static_method": static_method, 
32        "fool": fool}
33 
34 # Creating Spam class dynamically
35 Spam = type(cls_name, bases, dct)
36 
37 Spam.class_method()
38 Spam.static_method()
39 
40 s = Spam(1, 2)
41 s.fool()
