对于我自己的自我开发项目，我正在用python创建John Conway的生活游戏，但遇到了一个问题。我的代码正在编译，没有错误，但是在执行时它没有像我期望的那样运行。我的代码如下：
from tkinter import *
from random import *
import time
import copy
PIXEL_SIZE = 10
ROW = 910
COLUMN = 700
#updated_grid = [[]]
def create_grid(r, c):
grid = []
for row in range(0, r):
grid2 = []
for column in range(0, c):
grid2.append(randint(0, 1))
grid.append(grid2)
return grid
grid = create_grid(ROW, COLUMN)
updated_grid = create_grid(ROW, COLUMN)
def draw_grid():
for row in range(0, ROW):
for column in range(0, COLUMN):
if grid[row][column] == 1:
x0 = row*PIXEL_SIZE
y0 = column*PIXEL_SIZE
x1 = x0+PIXEL_SIZE
y1 = y0+PIXEL_SIZE
canvas.create_rectangle(x0, y0, x1, y1, fill='red')
def apply_rules():
for row in range(1, ROW - 1):
for column in range(1, COLUMN - 1):
neighbours_count = 0
# will count the neighbours for each cell
neighbours_count += grid[row-1][column-1] # top left
neighbours_count += grid[row][column-1] # top center
neighbours_count += grid[row+1][column-1] # top right
neighbours_count += grid[row-1][column] # middle left
neighbours_count += grid[row+1][column] # middle right
neighbours_count += grid[row-1][column+1] # bottom left
neighbours_count += grid[row][column+1] # bottom center
neighbours_count += grid[row+1][column+1] # bottom right
# Game Of Life rules:
# alive cell rules
if grid[row][column] == 1:
if neighbours_count < 2: # rule 1 any live cell with fewer than two live neighbours dies, as if by underpopulation
updated_grid[row][column] = 0
elif neighbours_count == 2 | neighbours_count == 3: # rule 2 any live cell with two or three live neighbours lives on to the next generation
updated_grid[row][column] = 1
elif neighbours_count > 3 & neighbours_count <= 8: # rule 3 any live cell with more than three live neighbours dies, as if by overpopulation
updated_grid[row][column] = 0
else:
updated_grid[row][column] = 0
elif grid[row][column] == 0: # dead cells rule 4 any dead cell with exactly three live neighbours becomes a live cell, as if by reproduction
if neighbours_count == 3:
updated_grid[row][column] = 1
else:
updated_grid[row][column] = 0
for row in range(0, ROW):
for column in range(0, COLUMN):
grid[row][column] = updated_grid[row][column]
def one_cycle():
apply_rules()
draw_grid()
window.after(1, one_cycle)
window = Tk() # creates the window for the game
window.title('Game Of Life Python') # is the game title written on the window
canvas_frame = Frame(window) # creates a frame on the window to hold the canvas
game_title = Frame(window) # creates a frame on the window to display the game title (which will be a label)
start_button = Button(window, text='Start Game', command=one_cycle) # creates a button which will be used to start the game
canvas = Canvas(canvas_frame, width=ROW, height=COLUMN, background='black') # creates the canvas used to the draw the game of life
game_title_label = Label(game_title, text='Game Of Life', font='Helvetica 20 bold', fg='grey') # creates the label for the game title which will be placed in a frame
canvas.grid(row=0, column=0) # places the canvas onto the canvas_frame
canvas_frame.grid(row=1, column=1) # places the canvas_frame onto the window
game_title_label.grid(rowspan=2, column=0) # places the title of the game onto the game_title frame
game_title.grid(row=0, columnspan=2) # places the frame for the game title onto the window
start_button.grid(rowspan=2, column=1) # places the start onto the window
window.mainloop()
从遍历代码开始，我只能认为错误出在appy_rules（）方法中（我可能是错误的），但是我仍然无法弄清楚为什么动画无法正确运行。我是python新手，所以非常感谢您能够提供的任何帮助，再次感谢您。
我看到两件事：
您根据需要创建了100倍的矩形，这就是为什么它会变慢的原因。使用：
PIXEL_SIZE = 10
ROW = 91 # One tenth of original value
COLUMN = 70 # One tenth of original value
您可以将画布创建为：
canvas = Canvas(canvas_frame, width=PIXEL_SIZE*ROW,
height=PIXEL_SIZE*COLUMN, background='black')
然后像以前一样使用ROW＆COLUMN。否则，您将在画布上为每个draw_grid()创建910 * 700矩形。
然后，在绘制画布时，您不会从画布上删除先前的矩形。只需将删除语句添加到draw_grid()：
def draw_grid():
canvas.delete('all')
# rest of code...
我尚未检查您的规则是否按预期工作，但这应该是一个开始。
通常，良好的做法是在代码中放置一堆测试打印函数，以便通过查看最后打印的字符串来查看代码失败的地方。编写这些字符串是为了描述代码刚刚执行的操作。尝试在您认为代码失败的地方执行此操作。
