Decorators run before function it is decorating is called?

Question

As an example:

def get_booking(f=None):
    print "Calling get_booking Decorator"
    def wrapper(request, **kwargs):
        booking = _get_booking         


        

Answer 1

A decorator is called as soon as the decorated function is defined. It is equivalent to writing something like this:

def __do_stuff(...):
    ...

do_stuff = get_booking(__do_stuff)
