Question

这是我试图显示图像的代码。嗯..首先应该在屏幕上显示4张卡片;但是，只有2个。我不知道为什么会这样。我真的需要帮助。

def __init__(self):
    Frame.__init__(self)
    self.master.title("Black Jack")
    blackjack = Blackjack()
    self.grid()

    self._playerCardImage = PhotoImage(file=str(blackjack._player._cards[0].fileName))
    self._playerCardLabel = Label(self, image = self._playerCardImage)
    self._playerCardLabel.grid(row=0, column=0)


    self._playerCardImage1 = PhotoImage(file=str(blackjack._player._cards[1].fileName))
    self._playerCardLabel1 = Label(self, image = self._playerCardImage1)
    self._playerCardLabel1.grid(row=0, column=1)

    self._dealerCardImage = PhotoImage(file=str(blackjack._dealer._cards[0].fileName))
    self._dealerCardImage = Label(self, image = self._dealerCardImage)
    self._dealerCardImage.grid(row=0, column=2)

    self._dealerCardImage1 = PhotoImage(file=str(blackjack._dealer._cards[1].fileName))
    self._dealerCardImage1 = Label(self, image = self._dealerCardImage1)
    self._dealerCardImage1.grid(row=0, column=3)

Answer 1

前两张卡片的前两行代码：

self._playerCardImage = PhotoImage(file=str(blackjack._player._cards[0].fileName))
self._playerCardLabel = Label(self, image = self._playerCardImage)
self._playerCardLabel.grid(row=0, column=0)

最后2张代码的最后2行代码：

self._dealerCardImage1 = PhotoImage(file=str(blackjack._dealer._cards[1].fileName))
self._dealerCardImage1 = Label(self, image = self._dealerCardImage1)
self._dealerCardImage1.grid(row=0, column=3)

您正在重新初始化_dealerCardImage1作为标签你需要将alst 2行改为：

self._dealerCardImage1 = PhotoImage(file=str(blackjack._dealer._cards[1].fileName))
self._dealerCardLabel1 = Label(self, image = self._dealerCardImage1)
self._dealerCardLabel1.grid(row=0, column=3)

Answer 2

在另一个答案的问题中，您询问是否可以循环创建图像。没有什么可以阻止你做那件事。

例如，如果您想创建4张牌手，则可以执行以下操作：

def __init__(self):
    Frame.__init__(self)
    self.master.title("Black Jack")
    blackjack = Blackjack()
    self.grid()

    self._images = []
    self._labels = []
    for column in range(4):
        image = PhotoImage(file=str(blackjack._player._cards[column].fileName))
        label = Label(self, image = image)
        label.grid(row=0, column=column)

        self._images.append(image)
        self._labels.append(label)
