1,679 PointsDecorator which accepts an argument
How can I make a decorator that takes an argument? Suppose I want a function to repeat as many times as I want by using a decorator .as example @decorator(argument)

231,236 PointsA decorator that has parameter(s) must return a function which takes a function argument and returns another function that calls it. So essentially, it has to return a regular decorator:
def decorator(argument):
def middle(func): # this would be a typical decorator by itself
def inner(*args, **kwargs):
func(*args, **kwargs)
return inner
return middle
If your head hasn't exploded yet, you might investigate callable objects and partials, which can give you more elegant ways of doing this kind of thing.
