Python 为什么索引器:列表索引超出范围。当列表索引不能超出范围时?

Python 为什么索引器:列表索引超出范围。当列表索引不能超出范围时?,python,python-2.7,tkinter,Python,Python 2.7,Tkinter,我一直在制作一个骰子游戏,当我到达将图像分配给每个Tkinter标签以便骰子显示的部分时,我开始出现以下错误: Exception in Tkinter callback Traceback (most recent call last): File "C:\Python27\lib\lib-tk\Tkinter.py", line 1486, in __call__ return self.func(*args) File "C:/Users/Logan/Desktop/Dic

我一直在制作一个骰子游戏,当我到达将图像分配给每个Tkinter标签以便骰子显示的部分时,我开始出现以下错误:

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Python27\lib\lib-tk\Tkinter.py", line 1486, in __call__
    return self.func(*args)
  File "C:/Users/Logan/Desktop/Dice/dicelab2.py", line 56, in rollDice
    self.dice[i].roll()
  File "C:/Users/Logan/Desktop/Dice/dicelab2.py", line 35, in roll
    self.display.config(image=Photolist[self.value-1])
IndexError: list index out of range
现在列表中有6个条目,我从self调用它。价值Self.value应该是1到6之间的随机整数。在我调用它之前,我减去1,所以它应该在照片列表的索引内。还有什么可能导致此错误? 这是我的密码:

import Tkinter
import random
Photolist=[]

class Die:

    def __init__(self,frame):        
        self.value = random.randint(1,6)
        print self.value
        photo1=Tkinter.PhotoImage(file="1.gif")
        photo2=Tkinter.PhotoImage(file="2.gif")
        photo3=Tkinter.PhotoImage(file="3.gif")
        photo4=Tkinter.PhotoImage(file="4.gif")
        photo5=Tkinter.PhotoImage(file="5.gif")
        photo6=Tkinter.PhotoImage(file="6.gif")

        Photolist=[photo1,photo2,photo3,photo4,photo5,photo6]

          relief='ridge',
          borderwidth=5,
          bg='white')
        self.display.pack(side='left')

    def roll(self):
        self.value = random.randint(1,6)
        print self.value
        self.display.config(image=Photolist[self.value-1])

class DiceRoller:
    def __init__(self):
        gameWin = Tkinter.Tk()
        gameWin.title('Dice Roller')
        diceFrame = Tkinter.Frame(gameWin)
        self.dice = [ ]
        for i in range(5):
            self.dice.append(Die(diceFrame))

        rollBtn = Tkinter.Button(gameWin,
          text='Roll Again',
          command=self.rollDice,
          font=('Courier New',30)) 
        diceFrame.pack()
        rollBtn.pack(side='bottom')
        gameWin.mainloop()

    def rollDice(self):
        for i in range(5):
            self.dice[i].roll()


dice = DiceRoller()
dice

在您的代码中,您有
Photolist=[]
所以您试图访问空列表,而不是类中的列表,我将其更改为一个属性,这样您现在就不会有问题了

天哪!我怎么会错过呢??非常感谢。不用担心,randint是一个例外,它比正常值更容易出错,通常范围的上限不包含在内。我尝试了你的建议,将范围更改为“random.randint(1,5)”,但我仍然得到相同的错误。发布整个回溯时+1。太多人没有。你有没有试过检查实际值,看看你的假设是否正确?
