What is "@" used for ?

[gops]

Hi.

I am noob in python. while reading some source code I came across ,
this funny thing called @ in some function ,

def administrator(m ethod):
@functools.wrap s(method)
def wrapper(self, *args, **kwargs):
user = users.get_curre nt_user()
if not user:
if self.request.me thod == "GET":

self.redirect(u sers.create_log in_url(self.req uest.uri))
return
raise web.HTTPError(4 03)
elif not users.is_curren t_user_admin():
raise web.HTTPError(4 03)
else:
return method(self, *args, **kwargs)
return wrapper

now what is that "@" used for ? I tried to google , but it just omits
the "@" and not at all useful for me(funny!! :D)

It will be enough if you can just tell me some link where i can look
for it..

Thank you in advance. :D

@ is decorator. It's a syntax sugar, see this example:
class A(object):
@decorate
def blah(self):
print 'blah'

is the same as:
class A(object):
def blah(self):
print 'blah'
blah = decorate(blah)

Now you know the name, I guess google will help you find the rest of
the explanation.
