用于在tkinter画布上放置图像的生成器

import tkinter as tk

def image_generator(canvas):
    # 生成器函数，用于生成图像坐标和路径
    images = [
        {'x': 100, 'y': 100, 'path': 'image1.png'},
        {'x': 200, 'y': 200, 'path': 'image2.png'},
        {'x': 300, 'y': 300, 'path': 'image3.png'}
    ]
    for image in images:
        # 在画布上放置图像
        img = tk.PhotoImage(file=image['path'])
        canvas.create_image(image['x'], image['y'], image=img)
        yield

# 创建主窗口和画布
root = tk.Tk()
canvas = tk.Canvas(root, width=500, height=500)
canvas.pack()

# 创建生成器对象
generator = image_generator(canvas)

# 每次调用next()方法，生成器会在画布上放置一个图像
next(generator)

# 进入主循环
root.mainloop()
