Build a Player Interface - Build a Player Interface

Tell us what’s happening:

Hi guys,

I don’t understand what is wrong with the code. I fails the test 11, 12, 13, 23, 25. Basically, like the methods make_move and level_up (from class Pawn) don’t work.

If I try to declare an instance of Player or Pawn, nothing works because abstract class Player/Pawn can’t be initialized with abstract method level_up

Your code so far

from abc import ABC, abstractmethod
import random

class Player(ABC):
    def __init__(self):
        self.moves = []
        self.position = 0,0
        self.path = [self.position]
    
    def make_move(self):
        move = random.choice(self.moves)
        self.position=(self.position[0] + move[0], self.position[1] + move[1])
        self.path.append(self.position)
        return self.position
    
    @abstractmethod
    def level_up(self):
        pass

class Pawn(Player):
    def __init__(self):
        super().__init__()
        self.moves = [(0, 1), (0, -1), (-1, 0), (1, 0)]
    @abstractmethod
    def level_up(self):
        self.moves += [(1, 1), (1, -1), (-1, -1), (-1, 1)]
        
#player = Player()
#player.make_move()
#pawn = Pawn()
#pawn.make_move()

Hi @katerynaguguieva,

You are so, so close. Check your definitions for level_up.

Should there be a 2nd declaration for an @abstractmethod in the class that inherits from the base class? Edit: fixed typo

Happy Coding!

OMG so silly….. I though I tried to delete the second decorator. Thank you a lot!
