Let me give you an example to illustrate what Martijn wrote:

Suppose you needed a file object to connect to some chunk of memory.  In
other languages, you would need to inherit from the Python file object
in order to ensure that random functions that expect file objects would
still work.  In Python, that's completely unnecessary.  It's probably a
lot simpler to create your own class, complete with open(), close(),
read(), and write() methods -- and because you've maintained *interface*
consistency, you can use your new class *ANYWHERE* a file object would
go.
