Decorator Arguments — Parameterised Decorators

"Basic decorators are powerful. But sometimes you want @retry(times=3) or @validate(min_amount=0.01, max_amount=9999) or @log(level='DEBUG'). Decorators with arguments need one extra level of nesting — a factory function that takes the arguments and returns the actual decorator. It looks like three levels of indentation, but the logic is straightforward once you see the pattern. Today you build the parameterised versions of the budget dashboard's decorators."
