Question

这是生命游戏计划。当我测试它时，我的周围（row，col）函数返回0，即使配置文件指示将制作8个方格＆＃34; LIVE。＆＃34;刚刚打开配置文件后打印电路板就进行了测试，但事实证明并没有使指示的方块说“现场”，“真实”。那些“活着”的人说＆＃39;没有＆＃39;所以没有＆＃39; LIVE＆＃39;正在计算价值。

[[None，None，None，0,0,0,0]，[None，0，None，0,0,0,0]，[None，None，None，0,0,0,0] ]，[0,0,0,0,0,0,0]，[0,0,0,0,0,0,0]，[0,0,0,0,0,0,0]， {0,0,0,0,0,0,0]是我print board时得到的。无法看到我在这里失踪的东西？

LIVE = 1
DEAD = 0

def board(canvas, width, height, n):
    for row in range(n+1):
        for col in range(n+1):
            canvas.create_rectangle(row*height/n,col*width/n,(row+1)*height/n,(col+1)*width/n,width=1,fill='black',outline='green')                      

n = int(raw_input("Enter the dimensions of the board: "))
width = n*25
height = n*25

from Tkinter import *
import math

window=Tk()
window.title('Game of Life')

canvas=Canvas(window,width=width,height=height,highlightthickness=0)
canvas.grid(row=0,column=0,columnspan=5)

board = [[DEAD for row in range(n)] for col in range(n)]

rect = [[None for row in range(n)] for col in range(n)]


for row in range(n):
    for col in range(n):      
        rect[row][col] = canvas.create_rectangle(row*height/n,col*width/n,(row+1)*height/n,(col+1)*width/n,width=1,fill='black',outline='green') 

#canvas.itemconfigure(rect[2][3], fill='red') #rect[2][3] is rectangle ID

#print rect

f = open('filename','r') #filename is whatever configuration file is chosen that gives the step() function to work off of for the first time
for line in f:
    parsed = line.split()
    print parsed
    if len(parsed)>1:
        row = int(parsed[0].strip())
        col = int(parsed[1].strip())
        board[row][col] = LIVE
        board[row][col] = canvas.itemconfigure(rlist[row][col], fill='red')        

def surrounding(row,col):
    count = 0
    if board[(row-1) % n][(col-1) % n] == LIVE:
        count += 1
    if board[(row-1) % n][col % n] == LIVE:
        count += 1
    if board[(row-1) % n][(col+1) % n] == LIVE:
        count += 1
    if board[row % n][(col-1) % n] == LIVE:
        count += 1
    if board[row % n][(col+1) % n] == LIVE:
        count += 1
    if board[(row+1) % n][(col-1) % n] == LIVE:
        count +=1
    if board[(row+1) % n ][col % n] == LIVE:
        count += 1
    if board[(row+1) % n][(col+1) % n] == LIVE:
        count += 1
    print count
    return count

surrounding(1,1)

您要两次分配board嵌套列表中的项目：

    board[row][col] = LIVE
    board[row][col] = canvas.itemconfigure(rlist[row][col], fill='red')

第一个将1分配给适当的值，第二个将1替换为None，因为这是使用这些参数调用时canvas.itemconfigure的返回值。我怀疑（没有测试它）你应该简单地从第二个语句中删除作业：

    board[row][col] = LIVE
    canvas.itemconfigure(rlist[row][col], fill='red')

这可能仍有问题（例如，rlist需要rect，或许？），但应解决None值的问题。

为什么价值被制成＆＃34;无＆＃34;而不是＆＃34; LIVE＆＃34;？
