python store variable in function and use it later

Question

is it possible to store a variable from a while loop to a function and then call that same variable from the function at the end of the loop

for eg:during while loop, p

Answer 1

As much as this is a bad idea I like applying weird solutions so here

class Store(object):
    def __init__(self, f):
        self.f = f
        self.store = None

    def __call__(self, *args):
        self.store = self.f(*args)

@Store        
def test(a,b,c):
    return a+b+c

print test(1,2,3)
print test.store

Decorate the function with Store then call function.store to get what you called in it, if the function is never called it returns a single None, you could make it raise an exception but personally I didn't want to.
