Here's the new type at work:
>>> print(defaultdict) # show our type
- <class 'test.test_descrtut.defaultdict'>
+ <class '%(modname)s.defaultdict'>
>>> print(type(defaultdict)) # its metatype
<class 'type'>
>>> a = defaultdict(default=0.0) # create an instance
>>> print(a) # show the instance
{}
>>> print(type(a)) # show its type
- <class 'test.test_descrtut.defaultdict'>
+ <class '%(modname)s.defaultdict'>
>>> print(a.__class__) # show its class
- <class 'test.test_descrtut.defaultdict'>
+ <class '%(modname)s.defaultdict'>
>>> print(type(a) is a.__class__) # its type is its class
True
>>> a[1] = 3.25 # modify the instance
>>> print(sortdict(a.__dict__))
{'default': -1000, 'x1': 100, 'x2': 200}

class defaultdict2(dict):
__slots__ = ['default']
... print("classmethod", cls, y)
>>> C.foo(1)
- classmethod <class 'test.test_descrtut.C'> 1
+ classmethod <class '%(modname)s.C'> 1
>>> c = C()
>>> c.foo(1)
- classmethod <class 'test.test_descrtut.C'> 1
+ classmethod <class '%(modname)s.C'> 1
>>> class D(C):
... pass
>>> D.foo(1)
- classmethod <class 'test.test_descrtut.D'> 1
+ classmethod <class '%(modname)s.D'> 1
>>> d = D()
>>> d.foo(1)
- classmethod <class 'test.test_descrtut.D'> 1
+ classmethod <class '%(modname)s.D'> 1
This prints "classmethod __main__.D 1" both times; in other words, the
class passed as the first argument of foo() is the class involved in the
>>> E.foo(1)
E.foo() called
- classmethod <class 'test.test_descrtut.C'> 1
+ classmethod <class '%(modname)s.C'> 1
>>> e = E()
>>> e.foo(1)
E.foo() called
- classmethod <class 'test.test_descrtut.C'> 1
+ classmethod <class '%(modname)s.C'> 1
In this example, the call to C.foo() from E.foo() will see class C as its
first argument, not class E. This is to be expected, since the call
specifies the class C. But it stresses the difference between these class
methods and methods defined in metaclasses (where an upcall to a metamethod
would pass the target class as an explicit first argument).
