卡片中的选择排序

我目前正在尝试在添加卡片时将选择排序实施到一系列卡片中。这是我当前的代码。我了解选择排序应该如何工作，并且只是在寻找有关如何开始在我的add函数中实现选择的建议。

手班 newHand（object）类：

def __init__(self, label = ""):
    """
    create an empty collection of cards with the given label
    """
    self.label = label
    self.cards = []


def add(self, card):
    """
    # Implements selection sort
    pre: card is a Card
    post: appended the card to the hand and sorts the deck
    """

    self.cards.append(card)


def sort(self):
    """
    post: arrange the cards in decending order
    """
    cards0 = self.cards
    cards1 = []
    while len(cards0) > 0:
        card = max(cards0)
        cards0.remove(card)
        cards1.append(card)
    self.cards = cards1


def dump(self):
    """
    post: outputs the contents in the hand
    """

    print(self.label + "'s Cards: ")
    for card in self.cards:
        print("\t", card)
