为什么我的图形窗口崩溃​​了？ [Zelle图形]

Question

我试图用Python创建生命游戏，但是由于某些原因，我的图形窗口在“运行模拟”功能期间崩溃。为什么会这样呢？日志上没有错误。

 from graphics import *  #Using zelle graphics module for Python
S=20 #Size of each cell. The bigger the number the bigger it is
class Cell: #Cell is a rectangular box. Can be alive or dead
    def __init__(self,window,x,y,alive):
        self.window=window
        self.alive=alive
        self.x=x
        self.y=y
        self.rectangle=Rectangle(Point(x*S,(y*S)+S),Point((x*S)+S,y*S))
        self.draw(x,y,self.window) 

    def draw(self,x,y,window):
        self.rectangle.setFill("black")
        self.rectangle.draw(window)

    def getX(self):
        return self.x*S

    def getY(self):
        return self.y*S+S

    def die(self):
        self.rectangle.setFill("black")
        self.alive=False

    def becomeAlive(self,window):
        self.rectangle.setFill("white")
        self.alive=True

    def isAlive(self):
        return self.alive

    def clickedOn(self,mouseX,mouseY):
        if (mouseX>self.getX() and mouseX<self.getX()+S and mouseY<self.getY()+S and mouseY<self.getY()):
            return True
        else:
            return False

    def totalNeighbours(self,cell0,cell1,cell2,cell3):
        if(cell0.isAlive() and cell0.isAlive() and cell0.isAlive() and cell0.isAlive()):
            return True


def createGraphics():    
    win=GraphWin("Game of Life!",1000,1000)
    return win

def createGrid(window):   #Creating the grid of cell objects
    cellList=[]
    for x in range(150):
        for y in range(150):
            cell=Cell(window,x,y,alive=False)
            cellList.append(cell)

    for i in range(10):
        getM=window.getMouse()
        j=0
        for cells in cellList:
            if cellList[j].clickedOn(getM.getX(),getM.getY()): #Checking whether the cell has been clicked.

                cellList[j].becomeAlive(window) 
                break
            else:
                j=j+1

    return cellList


def runSimulation(window,cellList):  #At this part my graphics window ceases functioning and the program crashes
    for i in range(10000000000):
        j=150
        for cell in cellList:
            if cell.isAlive():
                if cell.totalNeighbours(cellList[j-1],cellList[j+1],cellList[j+150],cellList[j-150])==4:
                    cellList[j].die()

            j=j+1

def main():
    window=createGraphics()
    cellList=createGrid(window)
    runSimulation(window,cellList)

main()

当我说“崩溃”时，是指程序停止运行，并且图形窗口没有响应。我以前遇到过这些问题，通常我只需要在shell配置中使用Tkinter gui，但是这次不起作用。
