constructor chaining?

[Mark Nenadov]

I am wondering how I can do constructor chaining with Python. 

For example, if I had a base class called "Media" and a child class
called "Book", how would I call the Media's __init__ constructor from
within the Book's __init_constructor?

In PHP I know you can just refer to the name of the parent's constructor.
In Java I believe you can call "super()". How can I do this in Python?

Thanks in advance.
