What is the meaning of "@" above "def"?

Question

from django.views.decorators.http import require_http_mothods

@require_http_methods(["GET", "POST"])
def my_view(request):
    pass

There is a "@" in above example. But I could not figure out that. Thanks in advance. :)

it's the [decorator](http://en.wikipedia.org/wiki/Python_syntax_and_semantics#Decorators). — Puffin GDI, Jan 16 '14 at 07:55

@ is used to decorate a function. This mechanism is called a decorator.

A decorator is a function that will modify the behavior of another function.

In your case, the require_http_methods decorator checks that the request is a GET or a POST method before calling the my_view function.

It's a very powerful mechanism and I do recommend to spend a little time for understanding it. You can start with this tutorial

I hope it helps
