python problem!!!

The Problem In previous assignments we have created a Character class for our characters and a Squad class for creating a gang with various characters. In this assignment we want to create a new kind of squad: a defensive squad. Besides the leader and the regular members, a defensive squad will also include a medic (or healer). The medic is a normal character with the distinction that it can't be removed from the squad. In this assignment you must create a class for a defensive squad. Because a defensive squad is a particular case of a regular squad, you must provide an implemen- tation of the DefensiveSquad class that inherits from the Squad class. This inheritance will provide two important advantages: it will allow you to reuse most of the code you already implemented for the Squad class (we are not talking about copy-pasting the previous code) and it will also allow you to treat squads polymorphically. The DefensiveSquad class should have the following: 1. It must inherit from the Squad class. 2. The class constructor will receive the name of the squad and five members, the first member should be the leader, the fifth must become the medic. 3. The class constructor must call the constructor of the super class and then complete any other required operation. 4. You must use name mangling to make all these instance variables inaccessible from outside the class. 5. There must be a getter and a setter for the medic. 6. You must provide a design that guarantees that the medic can't be removed from the squad, without overriding the remove_member method from the Squad class. 7. The class must contain a method squad_size that will return the number of members in the squad (including the leader and the medic). 8. The class must contain a method get_member that will return a member given it's index (the medic should be the last member). Depending on your implementation you may have to overwrite this method to account for the medic, but you can reuse the code of the Squad class by calling it inside this method. 9. You must implement the __str__ method for printing the squad's info in a format similar to the one shown in the example. You must implement this method by reusing (calling the --str__ method from the super class and only add the information about the medic. 10. You must also provide appropriate docstring documentation for classes and methods. 11. Notice that if implemented correctly the DefensiveSquad class will provide the same functionality as the Squad class without having to provide an implementation for the remove_member, add_member and save_to_disk method. You must also add the following method to the Squad and DefensiveSquad classes: 1. A members_names method that must return a list with the names (only the names) of all the members of the squad (including the leader). 2. The DefensiveSquad class must also provide an implementation of this method that will first call the method in the super class and then add the name of the medic to the list. For this assignment you must provide two driver programs: 1. You must provide a driver script that creates five characters and add them to a defensive squad and save the squad to disk (remember the last member you pass in to the constructor will be the medic). Then you should remove all the five characters and save the squad to disk; because the medic can't be removed the squad will have only the medic (the leader should be removed because there is at least one person in the squad, this is a condition from the previous assignment). Finally you should add two characters to the squad, the first one the be added should automatically become the leader; then save the squad to disk and print it to console. 2. You must provide another driver program where you create enough characters to populate two squads, a normal squad and a defensive squad. In this program you must also write a function that given a list of squads will return a list with all the members on these squads. Notice that the squads in the list can be either a regular Squad or a DefensiveSquad. Because both classes implement the members_names method you can treat them polymorphically. Driver Script and Sample Run First Driver As shown in Figure 1, the first driver program creates five characters and add them to a defensive squad. Subsequently all the characters are removed and finally two characters are added to the squad. At each step the squad is saved to disk and the final squad is also printed to console. Figure 2 shows the console output after executing the first driver program. Figure 3 shows the content of the first saved file, with the inclusion of the medic. From this example you should be able to infer the content of the other two files. import * First we create the four initial characters for the squad henry = Character("Billy the Kid", "A dangerous outlaw", "Gunfighter", 3.2, 82) diana = Character("Diana Gold", "The richest merchant of the west", "Merchant", 5.4, 54) frank = Character("Frank the Creep", "Knows his knifes", "Butcher", 4.1, 40) james = Character("James Montgomery", "The fastest gun in the west", "Hired Gun", 2.1, 88) mary - Character("Mary Montgomery", "Magic Hands", "Nurse", 4.4, 18) # We create the squad and save it to disk squad - DefensiveSquad("A gang with a medic", henry, diana, frank, james, mary) the_leader = squad.get_member(e) the leader.

Second Driver In the second driver program you must create enough characters to populate two squads, a normal squad and a defensive squad. In this program you must also write a function (all_names) that given a list of squads will return a list with all the members on these squads. Notice that the squads in the list can be either a regular Squad or a DefensiveSquad. Because both classes implement the members_names method you can treat them polymorphically. Figure 4 shows the part of the code where the characters are instantiated, then the two squads are created and added to a list; finally the function all_names is called passing in the list with the squads.
