You could get something similar using an object, such as

class Hist(object):

    def __init__(self):
        self.vals = [None]

    def __call__(self, index=-1):
        return self.vals[index]

    def set(self, val):
        self.vals.append(val)

a = Hist()

a.set(5)
print a()

a.set('hi there')
print a()
print a(-2)

Which prints
5
hi there
5
