如何在tkinter canvas中一起移动多个对象？

import tkinter as tk

root = tk.Tk()
canvas = tk.Canvas(root, width=500, height=500)
canvas.pack()

objects = []

# 定义对象的初始位置和移动速度
object1 = {'id': canvas.create_rectangle(50, 50, 100, 100, fill='red'), 'dx': 1, 'dy': 1}
object2 = {'id': canvas.create_oval(200, 200, 250, 250, fill='blue'), 'dx': -1, 'dy': -1}

objects.append(object1)
objects.append(object2)

def move_objects():
    for obj in objects:
        canvas.move(obj['id'], obj['dx'], obj['dy'])
    
    # 循环调用move_objects函数来实现连续移动
    canvas.after(10, move_objects)

# 调用move_objects函数开始移动对象
move_objects()

root.mainloop()
