更改tkinter中按钮的颜色

尝试制作电梯模拟器时，遇到了问题。有4部电梯，当按下楼层号码时，它应该变成红色。这适用于1部电梯中的1'面板'，但不适用于每部电梯中的1'面板'。这里是我的代码：更改tkinter中按钮的颜色

def floorChooserButtons(self, eleNum, floors, yStart, yEnd, xStart, xEnd): 
    self.Buttons1 = [i for i in range(41)] 
    self.Buttons2 = [i for i in range(41)] 
    self.Buttons3 = [i for i in range(41)] 
    self.Buttons4 = [i for i in range(41)] 
    if(eleNum is 1): 
     xPos = xStart 
     yPos = yStart 
     for floor in floors: 
      if(yPos == yEnd): 
       xPos = xPos + 1 
       yPos = yStart 
      if(xPos == xEnd-1): 
       yPos = yStart+2 
      self.Buttons1[floor] = tk.Button(self, width=3, text=floor, 
       command = lambda f=floor: self.chooser(f, eleNum)) 
      self.Buttons1[floor].grid(row=xPos, column =yPos) 
      yPos = yPos + 1 
    elif(eleNum is 2): 
     xPos = xStart 
     yPos = yStart 
     for floor in floors: 
      if(yPos == yEnd): 
       xPos = xPos + 1 
       yPos = yStart 
      if(xPos == xEnd-1): 
       yPos = yStart+2 
      self.Buttons2[floor] = tk.Button(self, width=3, text=floor, 
       command = lambda f=floor: self.chooser(f, eleNum)) 
      self.Buttons2[floor].grid(row=xPos, column =yPos) 
      yPos = yPos + 1 
    elif(eleNum is 3): 
     xPos = xStart 
     yPos = yStart 
     for floor in floors: 
      if(yPos == yEnd): 
       xPos = xPos + 1 
       yPos = yStart 
      if(xPos == xEnd-1): 
       yPos = yStart+2 
      self.Buttons3[floor] = tk.Button(self, width=3, text=floor, 
       command = lambda f=floor: self.chooser(f, eleNum)) 
      self.Buttons3[floor].grid(row=xPos, column =yPos) 
      yPos = yPos + 1 
    elif(eleNum is 4): 
     xPos = xStart 
     yPos = yStart 
     for floor in floors: 
      if(yPos == yEnd): 
       xPos = xPos + 1 
       yPos = yStart 
      if(xPos == xEnd-1): 
       yPos = yStart+2 
      self.Buttons4[floor] = tk.Button(self, width=3, text=floor, 
       command = lambda f=floor: self.chooser(f, eleNum)) 
      self.Buttons4[floor].grid(row=xPos, column =yPos) 
      yPos = yPos + 1 
     self.QUIT = tk.Button(self, text="QUIT", fg="red", 
      command=root.destroy).grid(row = xPos, column = yPos) 


def chooser(self, index, eleNum): 
    print("Number", index, "pressed in elevator", eleNum) 
    if eleNum is 1: 
     self.Buttons1[index].configure(bg="red") 
    if eleNum is 2: 
     self.Buttons2[index].configure(bg="red") 
    if eleNum is 3: 
     self.Buttons3[index].configure(bg="red") 
    if eleNum is 4: 
     self.Buttons4[index].configure(bg="red")

eleNum是电梯的数量，它是1-4 yStart，YEND，XSTART，XEND都用于布局。

任何帮助将被粉碎。感谢

这是misindented代码更改字体颜色。 – hd1

@ hd1只是由于stackoverflow，我试图缩进它，它不允许我。它在我的代码中正确缩进。 – Swapnull

@MartynRushton：你是什么意思，它不会允许你？当然会的。用空格替换所有选项卡，插入代码，突出显示它，然后单击'{}'按钮。如果你希望人们努力回答你的问题，你应该努力去问。 –

可以更改按钮的颜色在许多方面

b = Button(background = 'red') 
b.config(background = 'red') 
b.configure(background = 'red') 
b['background'] = 'red' 

b = Button(bg = 'red') 
b.config(bg = 'red') 
b.configure(bg = 'red') 
b['bg'] = 'red'

您可以或fg
