Write a class called Person that has two private data members - the person's name and age. It should have an init method that takes two values and uses them to initialize the data members. It should have a get_age method. Write a separate function (not part of the Person class) called std_dev that takes as a parameter a list of Person objects and returns the standard deviation of all their ages (the population standard deviation that uses a denominator of N, not the sample standard deviation, which uses a different denominator). To calculate the standard deviation, you'll need to take a square root, which you can do by just using an exponent of 0.5. For example, the result of 9 ** 0.5 would be 3.0. Python does have a specific sqrt() function, but that involves importing a module, which we haven't covered yet. Here's a simple example of how your class and function could be used: p1 = Person("Kyoungmin", 73) p2 = Person("Mercedes", 24) p3 = Person("Beatrice", 48) person_list = [p1, p2, p3] answer = std_dev(person_list)
