结果

代码

import tkinter as tk
import random
t=tk.Tk()
t.geometry('450x450')
c=[[tk.Canvas() for i in range(9)] for j in range(9)]
color=['red','yellow','purple','cyan','orange','grey','black','green','blue']
l=0 #画布的列数量计数
h=0 #画布的行数量计数
while h<9:
    while l<9:
        r=random.randint(0,8)
        c[h][l].configure(bg=color[r])
        c[h][l].place(x=l*50,y=h*50)
        l+=1
    h+=1
    l=0
tk.mainloop()
