python - TypeError: 'Function' に必要な位置引数が 1 つありません: 'self'

Question

コード：

class App:

    root = Tk()
    button1 = Button()
    button2 = Button()
    button3 = Button()

    img1 = PhotoImage(file="blueBox.png")
    img2 = PhotoImage(file="redBox.png")
    deckImage = PhotoImage(file="blackBox.png")

以下の 3 つの関数のいずれかを呼び出そうとすると、エラーが発生します。

    def showcolor1(self):
        if self.card1 != 0:
            self.card2 = 1
        else:
            self.card1 = 1

        self.button1.configure(image=self.getArrayValue(0))
        self.button1.configure(state=DISABLED)
        self.setChoosenPicture(self.getArrayValue(0))

によって呼び出される関数は機能したshowcolor1/2/3ため、削除しました。Buttons コマンドでこれらの関数を呼び出すには問題があります。

    def showcolor2(self):
        if self.card1 != 0:
            self.card2 = 2
        else:
            self.card1 = 2

        self.button2.configure(image=self.getArrayValue(1))
        self.button2.configure(state=DISABLED)
        self.setChoosenPicture(self.getArrayValue(1))

    def showcolor3(self):
        if self.card1 != 0:
            self.card2 = 3
        else:
            self.card1 = 3

        self.button2.configure(image=self.getArrayValue(1))
        self.button2.configure(state=DISABLED)
        self.setChoosenPicture(self.getArrayValue(2))


    button1 = Button(master=root, text="", image=deckImage, state=NORMAL, command=showcolor1)
    button1.pack()
    button2 = Button(master=root, text="", image=deckImage, state=NORMAL, command=showcolor2)
    button2.pack()
    button3 = Button(master=root, text="", image=deckImage, state=NORMAL, command=showcolor3)
    button3.pack()

    root.mainloop()

a = App()

コード全体は次のとおりです。黒いボタンが 3 つ表示されます。そして、ボタン 1 を押すと、彼の色が変わるはずです。2 つのボタンを押すと、同じ色かどうかをチェックします。::

from tkinter import *
class App:
    
    root = Tk()
    testArray = [1, 2, 2]
    cAmount = 0
    card1 = 0
    card2 = 0
    button1 = Button()
    button2 = Button()
    button3 = Button()
    
    img1 = PhotoImage(file="blueBox.png")
    img2 = PhotoImage(file="redBox.png")
    deckImage = PhotoImage(file="blackBox.png")

    def checkCards(self):
        if self.testArray[self.card1] == self.testArray[self.card2]:
            print("CORRECT")
        elif self.testArray[self.card1] != self.testArray[self.card2]:
            print("FALSE")
            if self.card1 == 1 or self.card2 == 1:
                self.button1.configure(image=self.deckImage)
                self.button1.configure(state=NORMAL)
            if self.card1 == 2 or self.card2 == 2:

            self.cAmount = 0
        else:
            return

    def getArrayValue(self, buttonIndex):

        self.button1.configure(image=self.getArrayValue(0))
        self.button1.configure(state=DISABLED)
        self.setChoosenPicture(self.getArrayValue(0))

    def showcolor2(self):
        if self.card1 != 0:
            self.card2 = 2
        else:

        self.button2.configure(image=self.getArrayValue(1))
        self.button2.configure(state=DISABLED)
        self.setChoosenPicture(self.getArrayValue(1))

    def showcolor3(self):

        else:

        self.button2.configure(image=self.getArrayValue(1))
        self.button2.configure(state=DISABLED)
        self.setChoosenPicture(self.getArrayValue(2))


    button1 = Button(master=root, text="", image=deckImage, state=NORMAL, command=showcolor1)
    button1.pack()
    button2 = Button(master=root, text="", image=deckImage, state=NORMAL, command=showcolor2)
    button2.pack()

    button3.pack()

    root.mainloop()
