how to construct a binary-tree using python?

[hankssong]

Hi everyone, I'm wondering whether it's possible to construct a
binary-tree using python.
Since python don't have pointer, it can't dynamically allocate memory
like C language.
But some important data structures like linked list, binary-tree and
hash table are closely linked with dynamic memory technology.

Any help that can be provided would be greatly appreciated.

Thanks in advance
