編寫遞歸隨機變量的更好方法

Question

我知道這確實很糟糕，但這確實有效，這是我目前所學的唯一完成工作的方法。 因此，我在實踐中尋找一種“更好”的方式來編寫此代碼。

基本上，它顯示3個插槽的圖像，並且這3個插槽使用SLOT_PATTERN列出的隨機圖像來更改圖像。 使用edit_message更改圖像，以編輯之前的3個插槽圖像，並用給定列表中的隨機圖像替換它們。

client = discord.Client()

@client.event
async def on_message(message):

    SLOT_PATTERN = [':four_leaf_clover:', ':moneybag:', ':cherries:', ':lemon:', ':grapes:', ':poop:', ':bell:', ':chocolate_bar:', ':watermelon:', ':six:', ':seven:', ':crown:']

    wheel_pick1 = SLOT_PATTERN[random.randint(0, len(SLOT_PATTERN) - 1)]
    wheel_pick2 = SLOT_PATTERN[random.randint(0, len(SLOT_PATTERN) - 1)]
    wheel_pick3 = SLOT_PATTERN[random.randint(0, len(SLOT_PATTERN) - 1)]
    wheel_pick4 = SLOT_PATTERN[random.randint(0, len(SLOT_PATTERN) - 1)]
    wheel_pick5 = SLOT_PATTERN[random.randint(0, len(SLOT_PATTERN) - 1)]
    wheel_pick6 = SLOT_PATTERN[random.randint(0, len(SLOT_PATTERN) - 1)]
    wheel_pick7 = SLOT_PATTERN[random.randint(0, len(SLOT_PATTERN) - 1)]

只是做一個功能！

def wheel():
    return SLOT_PATTERN[random.randint(0, len(SLOT_PATTERN) - 1)]

以及時間列表：

INTERVALS = [0.25, 0.25, 0.5, 0.75, 1, 1]

然后：

def wheels(n):
    return ' '.join(wheel() for _ in range(n))

if message.content.lower().startswith("!slots"):
    slot = await client.send_message(message.channel, wheels(3))

    for interval in INTERVALS:
        time.sleep(interval)
        slot = await client.edit_message(slot, wheels(3))
