使用 Tkinter 編程還很陌生，我很難用它。我正在嘗試使用 python重新創建它，并且似乎是最合適的庫：Tkinter。
如視頻所示，我希望能夠看到我的代碼“正在運行”，并希望為迷宮創建添加一點睡眠。我目前只創建了網格和一個為其著色的函式。雖然，我無法一一獲得我的視窗著色矩形。添加睡眠會阻止程式，沒有它，所有顏色都會一起出現。
我見過的所有解決方案都在談論帶有文本修改的標簽，但我無法讓它為我作業。我錯過了什么嗎？
謝謝你的幫助 ！

uj5u.com熱心網友回復：
可以.after()用來模擬跑步效果。此外，最好創建一次要填充的矩形，然后使用.after()以下方法一一更新它們的顏色：
from tkinter import Tk, Canvas, Frame, BOTH
import random
class Labyrinth(Frame):
def __init__(self):
super().__init__()
self.master.title("Laby")
self.pack(fill=BOTH, expand=1)
def create_grid(self, square_side, laby_side):
grid = []
canvas = Canvas(self, width=laby_side*square_side, height=laby_side*square_side, bg='black', highlightthickness=0)
# create the to-be-filled rectangles
for y in range(1, laby_side, 2):
for x in range(1, laby_side, 2):
x1, y1 = x*square_side, y*square_side
grid.append(canvas.create_rectangle(x1, y1, x1 square_side, y1 square_side, fill='white'))
canvas.pack()
return canvas, grid
# create set of colors
colors = [f'#{x:03x}' for x in range(0x1000)]
# shuffle the colors in random order
random.shuffle(colors)
def color_grid(canvas, grid, i=0):
canvas.itemconfig(grid[i], fill=colors[i])
if i < len(grid)-1:
# adjust the delay to suit your running effect
canvas.after(5, color_grid, canvas, grid, i 1)
def main():
root = Tk()
laby = Labyrinth()
square_side = 10
laby_side = 51
canvas, grid = laby.create_grid(square_side, laby_side)
color_grid(canvas, grid)
root.mainloop()
if __name__ == '__main__':
main()
