Instatiating an abstract class child using classmethod. Can't attach mandatory classmethod. Help needed.

    # this does not work
    # TypeError: Can't instantiate abstract class Player with abstract methods choose_position 
    imported_player = Player.from_file('some_player') 

    players = [kuba, imported_player]
    board = Board(size=20, empty_character='-')

    tic_tac_toe = Game(players, board)

    tic_tac_toe.print_intro()
    tic_tac_toe.play()
