In this lab you will work with all the concepts you have learned about classes in Python and you will edit a Python module for the first time.

The main goals of this lab are:

• Editing and importing your first module.
• Defining classes with properties and methods.
• Creating and using instances of a class object.

This lab has two parts:

• First, you will need to modify the Python module included in this repository by following the lab instructions below. The module is called battle and it contains a file called soldiers.py, which you will need to edit.

• Second, you will import the module and use it to instantiate objects. Then, you will create a simple program using those objects. To do so, follow the instructions in the main.ipynb file included in the present repository.

You must deliver the following files with the corresponding solutions:

• soldiers.py
• main.ipynb

Upon completion, add your deliverables to git. Then commit and push your branch to the remote.

The Vikings and the Saxons are at war. Both are soldiers, however, they have their own particular characteristics such as fighting styles and stamina.

Your tasks for this challenge are:

• Complete the battle module. You will need to edit the soldiers.py file to complete the definition of the three different classes included in that file: Soldier, Viking and Saxon.
• Use the battle module to create the most epic battle ever.

To complete those tasks, follow the instructions below.

In part I, you will equip your soldiers for battle.

Your task is to modify the battle module. Open soldiers.py and edit the classes Soldier, Viking and Saxon so that they meet the requirements specified below:

Properties

Soldier must have two main properties: health and strength.

Methods

Soldier must have two methods:

• attack
  • Mustn't receive any arguments.
  • Must return the strength of the soldier.
• receive_damage
  • Must receive as an argument the damage inflicted to the soldier.
  • Must remove the received damage from the health property of the soldier.

A Viking is a Soldier with additional properties.

Inheritance Viking must inherit from Soldier. Vikings share the health and strength properties with soldiers, as well as the attack method.

Properties Apart from the inherited health and strength, Vikings must have an extra property called name.

Methods

• attack: this method must be inherited from Soldier.
• receive_damage: this Viking method is slightly more sofisticated than the Soldier one.
  • Must receive as an argument the damage inflicted to the soldier.
  • Must remove the received damage from the health property of the soldier.
  • If the Viking is still alive, the method must return "NAME has received DAMAGE points of damage".
  • If the Viking dies, the method must return "NAME has died in combat".
• battle_cry
  • Mustn't receive any arguments.
  • Must return "Odin Owns You All!".

A Saxon is a nameless and apathetic kind of Soldier: saxons have no name and no battle cry.

Inheritance Saxon must inherit from Soldier. Saxons share the health and strength properties with soldiers, as well as the attack method.

Properties All Saxon properties are inherited from Soldier.

Methods

• attack: this method must be inherited from Soldier.
• receive_damage: this Saxon method is slightly more sofisticated than the Soldier one.
  • Must receive as an argument the damage inflicted to the soldier.
  • Must remove the received damage from the health property of the soldier.
  • If the Saxon is still alive, the method must return "A Saxon has received DAMAGE points of damage".
  • If the Saxon dies, the method must return "A Saxon has died in combat".

In part II, the moment to fight has come! Prepare your armies and head to the battlefield!

Open the main.ipynb file and follow the instructions to simulate a war between saxons and vikings.
