decorators

[micseydel]

I now want to decorate this function so that the first argument is always multiplied by 4 and then added to the second argument.

From the way you describe it, your decorator will not care what the function it's decorating does. Am I correct in saying what you actually want is a decorator which multiplies the first argument by a value provided to the decorator, before calling the decorated function?

I believe that in either case, my example should be fairly adaptable. Feel free to give it a try, and we can work from there.
