Python сопрограмма времени нарезки

Question

Я учусь использовать сопрограммы отсюда, и в статье видео приводится пример в качестве примера

Мастер по шахматам Юдит Полгар проводит шахматную выставку, на которой играет несколько любительских игроков. У нее есть два способа проведения выставка: синхронно и асинхронно.

Предположения:

24 opponents
Judit makes each chess move in 5 seconds
Opponents each take 55 seconds to make a move
Games average 30 pair-moves (60 moves total)

Синхронная версия: Юдит играет по одной игре за раз, никогда по две в то же время, пока игра не будет завершена. Каждая игра занимает (55 + 5) * 30 == 1800 секунд или 30 минут. Вся выставка занимает 24 * 30 == 720 минут или 12 часов.

Асинхронная версия: Юдит перемещается из таблицы в таблицу, делая один ход за каждым столом. Она покидает стол и позволяет противнику сделать следующий шаг во время ожидания. Один ход на все 24 игры занимает Юдит 24 * 5 == 120 секунд или 2 минуты. Вся выставка сейчас вырезана до 120 * 30 == 3600 секунд или всего 1 час.

Рецензия взята отсюда https://youtu.be/iG6fr81xHKA?t=4m29s

Если бы я написал код для шахматной выставки, моя программа содержала бы 24 сопрограммы и должна была завершиться в течение 5 секунд и перейти к следующей сопрограмме.

Поэтому мой вопрос заключается в том, что в python пишется 24 функции, которые в значительной степени делают то же самое, что считается плохой практикой кодирования, и если да, что с этим можно сделать?.

Редактировать

Из этого примера https://github.com/prompt-toolkit/python-prompt-toolkit/blob/master/examples/other/coroutines-and-futures.py

Я вижу, что мы можем сделать 24 функции.

Answer 1

Это один из способов его реализации:

import asyncio


class Player:
    def __init__(self, name: str, seconds_per_turn: float):
        self.name = name
        self.seconds_per_turn = seconds_per_turn
        self.busy = asyncio.Condition()

    async def move(self, game):
        await self.busy.acquire()
        print(f'game {game.game_number} player {self.name} begins {self.seconds_per_turn} second move')
        await asyncio.sleep(self.seconds_per_turn)
        print(f'game {game.game_number} player {self.name} ends {self.seconds_per_turn} second move')
        self.busy.release()


class Game:
    def __init__(self, game_number: int, player1: Player, player2: Player, number_of_turns: int):
        self.game_number = game_number
        self.player1 = player1
        self.player2 = player2
        self.number_of_turns = number_of_turns

    async def start(self):
        print(f'game {self.game_number} started')
        for turn in range(1, self.number_of_turns + 1):
            print(f'game {self.game_number} turn #{turn}')
            await self.player1.move(self)
            await self.player2.move(self)
        print(f'game {self.game_number} ended')


if __name__ == '__main__':
    synchronous = False
    loop = asyncio.get_event_loop()
    judit = Player('judit', 5)
    for i in range(1, 25):
        opponent = Player(f'opponent {i}', 55)
        game = Game(i, judit, opponent, 30)
        if synchronous:
            loop.run_until_complete(game.start())
        else:
            asyncio.ensure_future(game.start())
    loop.run_forever()

Выход:

game 1 player judit begins 5 second move
