Save functions for re-using without re-execution

I tried to find some kind of things that allow to "save functions" such as: Once running the program (included some functions) and we will save functions's address in memory after that, we can re-use these functions without execution any more. Could you give me some ideas (in general or particular in Python, C/C++,...). I have googled this but I didn't get it :(. I was thinking of some kind of memory management (allocation, freedom of memory, resident memory...I guess) For example: I have a function with its address "at " (that is generated when program runs) How can I reuse them?! Thanks in advance

Well, in Python, functions are objects, so you can pass them around, assign them, and call them from any label you've used to alias them. You can also get the id (memory location/guid equivalent). If what you mean is memoization/lazy loading of data, there are a number of resources available on SO and through Google for doing that sort of thing. They generally look like:

class Foo(object):
    @staticmethod
    def get_val():
        try:
            return Foo.__val
        except AttributeError:
            #do run-once logic here, assign to Foo.__val
            return Foo.__val
