What does @ do in Python 3 (Pyglet)?

Question

I was trying out Pyglet via this tutorial when I noticed this portion of the code, which is not documented on the page.. I have not been able to find anything on it by searching the web either.

What exactly does it do? Can it be used with other objects?

    @window.event

It’s a [decorator](https://wiki.python.org/moin/PythonDecorators). — Ry-, Jan 16 '14 at 02:51

It "decorates" the following function/method/class

@window.event
def f(foo):
    return bar

Is equivalent to

def f(foo):
    return bar
f = window.event(f)
