what does 'objects being subclassable' mean?
Dive into Python -
Different programming languages define “object” in different ways. In some, i开发者_Python百科t means that all objects must have attributes and methods; in others, it means that all objects are subclassable. In Python, the definition is looser; some objects have neither attributes nor methods (more on this in Chapter 3), and not all objects are subclassable (more on this in Chapter 5).
I am coming from C++/Java
background.
To be subclassable means that you can inherit from them. e.g.
class Foo(object):
pass
object
here is subclassable because Foo can inherit from it.
In this context I think it is talking about Inheritance or Interfaces. As in, you can subclass a Human into Male and Female.
