Writing a generator that can be called like a regular function?

Hi there,

I have a function in a script that takes an object and returns a boolean depending on it's argument:

def test(person):
    return person.name == 'bob'

However, sometimes I might want to edit it to return true every nth call, regardless of the person. So maybe a generator?

def test(n):
     i=0
     while True:
        yield i%n==0
        i+=1

However, then (I believe) I have to modify the code where it's called to use the next method. I tried encapsulating the generator function within another function, but then the generator returns it's first value every call.

Is this even possible? Maybe there's a solution using decorators?
