有没有更高效的换卡方式？我最初的想法是通过输入来改变它们，例如：黑桃或红心 3。 但我尝试过，对于我的水平来说这太难了。所以我改变了主意，我将通过索引输入来更改卡片。所以我的问题是：如何改进换卡方式？

首先（有点不相关）：当你洗牌时，为什么不只处理前五张牌（并将它们从牌堆中删除），而不是随机提供牌并确保它们是唯一的：

deck = all_cards
shuffle(deck)
hand = deck[:5]
deck = deck[5:]

换卡时也应遵循相同的方法，例如：

while True:
    ans = input("Which cards you want to change (1-5, separated by comma): ")
    try:
        cardstochange = [int(i) for i in ans.split(",")]   # turn answer into list of integers (might raise an error)
        for cardidx in cardstochange:
            if cardidx < 1 or cardidx > 5:
                raise ValueError            # Raise an error 'cos the user can't count to 5
            hand[cardidx-1] = deck[0]       # -1 because the index start at 0
            deck = deck[1:]
        break;
    except Exception: # Catch any bs input here
        print("I didn't get you. Say again!")
