使用tkinter跟踪画布上每个多边形的每个点

import tkinter as tk

def track_points(event):
    x, y = event.x, event.y
    for polygon in polygons:
        for i in range(len(polygon)):
            px, py = polygon[i]
            if abs(x - px) < 5 and abs(y - py) < 5:
                print("Mouse is near point ({}, {}) of polygon".format(px, py))

root = tk.Tk()
canvas = tk.Canvas(root, width=400, height=400)
canvas.pack()

polygons = [
    [(50, 50), (100, 50), (100, 100), (50, 100)],
    [(150, 150), (200, 150), (200, 200), (150, 200)]
]

for polygon in polygons:
    canvas.create_polygon(polygon, outline='black', fill='white')

canvas.bind('<Motion>', track_points)

root.mainloop()
