Python create a python class called Person that defines two attributes name and age and the following methods: _init__ initializes the attributes name and age, both mandatory the methods set_name and set_age to affect a value to attributes name and age respectively the methods get_name and get_age to return the value for name and age respectively define the method age_diff that displays the difference of age between two objects of type Person Create a class Student that inherits the parent class Person. It redefines the method _init__ by reusing the _init_ method of Person, and also by initializing the attribute friends, which will always be initialized to an empty list. Define the method add_friend to add an element of type Student to the friend list. This method add an element to the list friend if and only if the element is not already in the list. Define the method _str_ to display the object of type Student as in the example. Define the method get_friends of the class Student. This method displays the elements of the list friend. The method get_friends follows the display as in the following example:

Python create a python class called Person that defines two attributes name and age and the following methods: __init__ initializes the attributes name and age, both mandatory the methods set_name and set_age to affect a value to attributes name and age respectively the methods get_name and get_age to return the value for name and age respectively define the method age_diff that displays the difference of age between two objects of type Person Create a class Student that inherits the parent class Person. It redefines the method _init__ by reusing the _init_ method of Person, and also by initializing the attribute friends, which will always be initialized to an empty list. Define the method add_friend to add an element of type Student to the friend list. This method add an element to the list friend if and only if the element is not already in the list. Define the method __str__ to display the object of type Student as in the example. Define the method get_friends of the class Student. This method displays the elements of the list friend. The method get_friends follows the display as in the following example:
