Why is my Python abc setup giving errors?

Hi
My PyCharm is giving surprising red-underlining on import abc, object, and from abc import
Up til now, my chess engine has been working on a player class, but I'd like it to be an abstract base class. I am re-designing it
Must I do any special entries in the Project Settings panel? my code below doesn't seem to be a problem,

My abc is :

import abc

class ChessPlayer(object):
    __metaclass__= abc.ABCMeta

    @abc.abstractmethod
    def get_white_move(self, white_moves):
        """white player chooses the best move for this turn"""
        return

    @abc.abstractmethod
    def get_black_move(self, black_moves):
        """black player chooses the best move for this turn"""
        return

Open in new window

My derivative class is:

import abc
from abc_base import ChessPlayer:


class RandomPlayer(Object):
# ToBeDone, once setup is correct

Open in new window

Thanks

Thanks a lot
I've done what you suggested, and there are some errors that I don't understand.

I did the name change for abc_base.py:

My RandomPlayer.py does appropriate implementations of the methods:

import abc, random
from abc_base import ChessPlayer


class RandomPlayer(ChessPlayer):
    def __init__(self):
        pass

    def get_white_move(self, white_moves):
            len =white_moves.len()
            print('get_white_move()')
            random_move_index = random.randint(0,len)
            white_move = white_moves[random_move_index]
            return white_move


    def get_black_move(self, black_moves):
        len = black_moves.len()
        print('get_black_move()')
        random_move_index = random.randint(0, len)
        black_move = black_moves[random_move_index]
        return black_move

Why does the instantiation of a randomPlayer fail in the engine class? :

import RandomPlayer


class ChessEngine:
    def __init__(self):

        white_player = RandomPlayer()


print('main')



engine = ChessEngine()
