Question

我在tkinter上创造了yahtzee游戏。我认为这将是一个很好的学习开始。我有一个错误说： UnboundLocalError：分配前引用的本地变量'Dice1Butt_clicks' 我已经尝试在代码开头将变量设置为全局变量，我尝试创建一个方法将所有变量设置为全局变量并在我使用变量时调用它但没有任何效果。

不确定我还能做什么？我可以在没有“+ =”的情况下工作，但我现在比以往任何时候都想要了解正在发生的事情以及为什么Python使一切变得复杂？顺便说一句，我正在使用python 2.7.13。你能帮帮忙吗？

from tkinter import *               #Import everything from Tkinter
from random import randint          #import random integer number generator
import tkinter.messagebox           #Import messagebox method

###########  Create main window, call it root  ###########
root = Tk()

在python中，您可以按名称访问全局变量，但是如果要更改它们（使用+ =， - =，=，...），则需要在中使用 global 关键字em>那个功能。

所以在你的情况下它应该是：

def updt_Dice1Butt():
    global Dice1Butt_clicks          # note this line
    Dice1Butt_clicks += 1
    if Dice1Butt_clicks > 2:
        Dice1Butt.configure(state=DISABLED)
    Dice1ran_no = randint(1,6)
    Dice1Butt['text'] = str('You drew: ') + str(Dice1ran_no)

依旧......

UnboundLocalError：在赋值之前引用的局部变量无效于全局赋值
