終於寫出我想要的點擊滑鼠在點擊處顯示點擊的座標(2023.10.29日)

from tkinter import *

r=Tk()

canvas=Canvas(r,width=1200,height=600)

canvas.pack()

def mouse(event):

    x=event.x

    y=event.y

    canvas.create_text(x,y-15,text="( {},{} )".format(x , y))

    canvas.create_oval(x-2,y-2,x+3,y+3,width=4) # 圓形

    canvas.pack()

r.bind("<Button-1>",mouse)

r.mainloop()
