是否可以在 Python 1 或 Python 2 中创建新类型（但不是新的 class）？

Question

Python 2.1.x 或更低版本中没有 object 类型。
这是三个文件：

#!/usr/bin/env python2
class foo: pass
print(foo)
print(repr(foo))
print(type(foo))

#!/usr/bin/env python2
class foo(object): pass
print(foo)
print(repr(foo))
print(type(foo))

#!/usr/bin/env python3
class foo(object): pass
print(foo)
print(repr(foo))
print(type(foo))

这是他们的输出：（仅供参考）

__main__.foo
<class __main__.foo at 0xf7d30e9c>
<type 'classobj'>

<class '__main__.foo'>
<class '__main__.foo'>
<type 'type'>

<class '__main__.foo'>
<class '__main__.foo'>
<class 'type'>

在Python3中，所有类型都是classes.
但是在Python1和Python2中，类型是“type”类型，classes是“classobj”类型。 class foo(object): pass生成的class只是“object”类型的childclass。
那么，是否可以在 Python 1 或 Python 2 中创建一个新类型（但不是新的 class）？如果是，如何？

No, that's why new-style classes were added: to eliminate the artificial distinction between classes and types. Old-style classes have type classobj, but they were effectively deprecated as soon as new-style classes were introduced in Python 2.2. Given the extreme age of the versions being asked about, this would probably be more suitable retrocomputing.stackexchange.com.

Is it possible to create a new type(but not a new class) in Python 1 or Python 2?

types

class
