What does @ do in Python 3 (Pyglet)?

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
Solution

  • 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)
