无效的命令名称".!label3"

Question

我正在创建一个游戏，当疫苗达到100时，游戏结束，用户被转移到胜利屏幕。见下文

import random
from tkinter import *
#creates new window
root = Tk()
#makes backdrop picture of map
C = Canvas(root, bg="black", height=780, width=1347)
C.grid(row=0,column=0)

#vaccine label creation and place
vaccineLabel=Label(root, text="10000", font ="algerian 25", bg = "Light Blue")
vaccineLabel.place(x=271 ,y=706, relwidth=1/5, relheight=0.1)

totalDeaths = 0
totalPopulation = 1
vaccineCount = 95
#loops until total deaths = population
def simulate_Count():

def update_Count():

#calls global variables
global vaccineCount

#vaccine determination
vaccine1 = random.randint(0,0)
vaccine2 = random.randint(0,0)
if vaccine1 == vaccine2:
vaccineCount += 1
#updates labels
vaccineLabel.config(text = f'Deaths:{vaccineCount}')

if vaccineCount == 100:
def victory_Screen():
#calls global root and deletes
global root
root.destroy()                           
#creates the window
root = Tk()
#assembles the dimension of the window, and the colour
C=Canvas(root, bg="black", height=780, width=1347)
C.grid(row=0, column=0)

#creates a label which will print the game title and places it in the correct dimensions
victoryLabel=Label(root, text=f"YOU HAVE WON! n IT ONLY TOOK YOU", bg="black", fg="light grey")
victoryLabel.place(x=0, y=0, relwidth=1, relheight=1)
victory_Screen()


update_Count()

#loops until deaths = population
if totalDeaths < totalPopulation:
root.after(1000, simulate_Count)
simulate_Count()

这给我带来了一个错误。当我销毁窗口并创建一个新窗口时，会显示新窗口。然而，由于某种原因，这些线路出现错误，错误类型为invalid command name ".!label3"

包含错误的行如下：

#updates labels
vaccineLabel.config(text = f'Vaccine: {vaccineCount}%')

错误似乎是update_Count()仍在尝试配置一个不存在的标签。任何帮助都将不胜感激！！

Answer 1

由于victory_screen函数破坏了包含疫苗标签的根窗口，因此引发了错误。因此，一旦根被破坏，标签就不复存在，因此您不再在其上使用.config。

要解决此问题，请检查疫苗计数<100，然后再运行vaccineLabel.config(text = f'Deaths:{vaccineCount}')。

这确保了疫苗标签在调用.config之前仍然存在。
