It's a decorator. The syntactic sugar for decorators is a Python 2.4 feature, but decorators by themselves are not. The 2.4 syntax is: @decorator def decorated(args): do_something and is just a shortcut for def decorated(args): do_something decorated = decorator(decorated) The decorator itself is any callable taking a callable as argument and returning a callable. The builtin types classmethod and staticmethod are decorators. > I try to google for it and don't seem to come up > with specific hit.. http://www.google.com/search?q=%2Bpython+%2B%40decorator gives me =~ 619 000 answers... > Does that mean using 2.3 is out of the question? I don't know if TG runs on 2.3.x, but as far as decorators are concerned, you can just use the 'explicit' syntax instead: class MyController(...): def my_action(...): ... my_action = expose(my_action) -- bruno desthuilliers développeur [EMAIL PROTECTED] http://www.modulix.com --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "TurboGears" group.
