from tkinter import * import random import time

class Ball: def _init_(self, canvas, color): self.canvas = canvas self.id = canvas.create_oval(10, 10, 25, 25, fill=color) self.canvas.move(self.id, 245, 100)
def draw(slef): pass

tk = Tk() tk.title('Game') tk.resizable(0, 0) tk.wm_attributes('-topmost', 1) canvas = Canvas(tk, width=500, bd=0, highlightthickness=0) canvas.pack() tk.update() ball=Ball(canvas, 'red') 有大师能告诉我这个代码为什么出错吗？求助求助求助！！！！
