Elves and Dwarves

Imagine that you have started developing your meta universe. In your universe, all players are divided into two races - Elves and Dwarves. Both races are divided into two groups. For elves, these are the ElfRanger and Druid classes. Dwarves have the DwarfWarrior and DwarfBlacksmith classes.

Thus, each player should be an instance of one of these four classes. But to have better code design, you should implement the abstract classes Elf, Dwarf and Player, where you can put the common logic.

The base class should be the Player class, which should have a single nickname attribute, where the player's name will be stored. It must also have two empty abstract methods get_rating, player_info, declared, thus we guarantee that all players in our universe will have them defined.

Two classes Elf and Dwarf should be inherited from the Player.

All elves like playing songs so Elf constructor should take an additional argument musical_instrument - and stored it in the protected attribute. Also, it should have a method play_elf_song that should print the following string: "{nickname} is playing a song on the {musical_instrument}"

All dwarves like delicious food so Dwarf constructor should take an additional argument favourite_dish - and stored it in the protected attribute. Also, it should have a method eat_favourite_dish that should print the following string: "{nickname} is eating {favourite_dish}"

Finally, create four classes: ElfRanger, Druid, DwarfWarrior and DwarfBlacksmith.

ElfRanger should be a child of Elf. Its constructor should take one additional parameter: bow_level - an integer that shows the quality of the bow. Constructor should store it in the protected attribute.

Druid should be a child of Elf. Its constructor should take one additional parameter: favourite_spell - the text of the favourite spell. Constructor should store it in the protected attribute.

DwarfWarrior should be a child of Dwarf. Its constructor should take one additional parameter: hummer_level - an integer that shows the power of the hummer. Constructor should store it in the protected attribute.

DwarfBlacksmith should be a child of Dwarf. Its constructor should take one additional parameter: skill_level - an integer that shows the level of blacksmith's skills. Constructor should store it in the protected attribute.

All of these classes should have implementations of player_info and get_rating methods.

player_info method should return:

  • "Elf ranger {nickname}. {nickname} has bow of the {bow_level} level" for ElfRanger instances
  • "Druid {nickname}. {nickname} has a favourite spell: {favourite_spell}" for Druid instances
  • "Dwarf warrior {nickname}. {nickname} has a hummer of the {hummer_level} level" for DwarfWarrior instances
  • "Dwarf blacksmith {nickname} with skill of the {skill_level} level" for DwarfBlacksmith instances

get_rating method should return:

  • 3 * bow_level for ElfRanger
  • length of favourite_spell for Druid
  • hummer_level + 4 for DwarfWarrior
  • skill_level for DwarfBlacksmith
ranger = ElfRanger(
    nickname="Nardual Chaekian",
    musical_instrument="flute",
    bow_level=7
)
ranger.get_rating() == 21
ranger.player_info() == "Elf ranger Nardual Chaekian. Nardual Chaekian has bow of the 7 level"
ranger.play_elf_song()  # "Nardual Chaekian is playing a song on the flute" 
warrior = DwarfWarrior(
    nickname="Thiddeal",
    favourite_dish="French Fries",
    hummer_level=7
)
warrior.get_rating() == 11
warrior.player_info() == "Dwarf warrior Thiddeal. Thiddeal has a hummer of the 7 level"
warrior.eat_favourite_dish()  # "Thiddeal is eating French Fries"

Write following functions:

  • calculate_team_total_rating - it should take list of Players and return the sum of the ratings for all team members
team = [
    Druid(nickname="Druid", musical_instrument="flute", favourite_spell="ABC"),
    ElfRanger(nickname="Ranger", musical_instrument="trumpet", bow_level=33),
]
calculate_team_total_rating(team) == 102  # 33 * 3 + 3
  • elves_concert - it should take a list of Elf and call play_elf_song method for each elf.
elves = [
    Druid(nickname="Nardual", musical_instrument="flute", favourite_spell="aaa"),
    ElfRanger(nickname="Rothilion", musical_instrument="trumpet", bow_level=33),
]
elves_concert(elves)
# "Nardual is playing a song on the flute"
# "Rothilion is playing a song on the trumpet"
  • feast_of_the_dwarves - it should take a list of Dwarf and call eat_favourite_dish method for each dwarf.
dwarves = [
    DwarfWarrior(nickname="Thiddeal", favourite_dish="French Fries", hummer_level=3),
    DwarfWarrior(nickname="Dwarf", favourite_dish="Caesar Salad", hummer_level=3),
]
feast_of_the_dwarves(dwarves)
# "Thiddeal is eating French Fries"
# "Dwarf is eating Caesar Salad"

Use the following project structure:

app/
    main.py
    players/
        player.py
        elves/
            elf.py
            elf_ranger.py
            druid.py
        dwarves/
            dwarf.py
            dwarf_warrior.py
            dwarf_blacksmith.py

All classes should be defined in the corresponding modules. Functions should be defined in the main.py module.

Note: Check your code using this checklist before pushing your solution.
