在Tkinter画布中更新多个create_text对象

import tkinter as tk

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

text1 = canvas.create_text(100, 100, text="Text 1")
text2 = canvas.create_text(200, 200, text="Text 2")
text3 = canvas.create_text(300, 300, text="Text 3")

def update_text():
    canvas.itemconfig(text1, text="Updated Text 1")
    canvas.itemconfig(text2, text="Updated Text 2")
    canvas.itemconfig(text3, text="Updated Text 3")

button = tk.Button(root, text="Update Text", command=update_text)
button.pack()

root.mainloop()
