使用 lambda 更新 Tkinter 按钮的文本会导致 Lambda 字符串作为标题弹出

Question

我目前正在使用 tkinter 来进行扑克模拟。我试图给每只手（由卡片按钮代表）一个文本来代表他们有多少钱。以下是发牌和返还资金的代码。

#This deals the card to each of the players
def dealCard():
   '''Deals the Card to Each of the players'''
   global handCount, cards, cardSuit, cardRank, hand
   for i in range(amountOfPlayers):
       hand = []
       while handCount < 2:
           card = changeCardHand()
           cardSuit = str(card.suit)
           cardRank = str(card.rank)
           cardImage = showCard(cardSuit, cardRank, width= 75, height = 100)
           image_listHand.append(cardImage)
           backImage = Image.open(f"PNG-cards-1.3/card_back_black.png")
           backImage = backImage.resize((75, 100))
           backImage = ImageTk.PhotoImage(backImage)
           back_imageList.append(backImage)
           cardButton = tkinter.Button(canvas, image = backImage, text = "0", compound = "bottom", command = lambda index = image_listHand.index(cardImage): [flipImage(index)])
           cardButton.config(text = lambda index = i: [getPlayerMoney(index)])
           button_list.append(cardButton)
           cardButton.place(x = (-25 * amountOfPlayers) + (50*(2*i+1) + 120*(i + 1)) + (handCount + 1)*80, y = (300))
           handCount = handCount + 1
           hand.append(card)
       cards.append(hand)
       handCount = 0 

这是退款代码

def getPlayerMoney(index):
    return str(money[index])

这是使用 Entry 来设置每个人开始的金额的代码。

def loadMoney():
    '''Loads the money into each of the players hands'''
    global potValue
    potValue = int(potEntry.get())
    for i in range(amountOfPlayers):
        money.append(potValue)
    potEntry.destroy()

但是，每张卡片的文本不是显示货币价值，而是 lambda 字符串

如何解决这个问题？

Answer 1

现在

text

是一个 lambda 函数。当您打印 lambda 函数时，它也会显示 lambda 字符串。 如果不需要，可以删除 lambda 函数。

cardButton.config(text = [getPlayerMoney(i)])

或者如果您需要 lambda 函数

func = lambda index = i: [getPlayerMoney(index)]
cardButton.config(text = func())
