Variable value is determined by function call

This is probably weird but I would like to declare a variable without a fixed value, but "linked" in some way to the result of a function. The goal is for the end user to manipulate a variable, but each time the variable's value is used, its value may change.

This is the current result I get:

from random import randint

def randomfun():
    return randint(1, 100)

an_int = randomfun
print an_int    # Print the function object
print an_int()  # Print the result of randomfun()

What I would like to get is print an_int to actually call randomfun() , but without having to add the parenthesis, and the type of an_int should be randomfun 's return type.

an_int is an object. It won't change its value unless you change it. However, you could change the way the object is represented:

from random import randint

class RandomFun(object):
    def __str__(self):
        return str(randomfun())

def randomfun():
    return randint(1, 100)

an_int = RandomFun()
print an_int    
print an_int    

yields (something like)
