我想单击tkinter entry来绑定，甚至返回三个不同的值给entry

import tkinter as tk

def get_value_1():
    entry.delete(0, tk.END)  # 清空entry中的内容
    entry.insert(tk.END, "Value 1")  # 在entry中插入新的值

def get_value_2():
    entry.delete(0, tk.END)
    entry.insert(tk.END, "Value 2")

def get_value_3():
    entry.delete(0, tk.END)
    entry.insert(tk.END, "Value 3")

root = tk.Tk()

entry = tk.Entry(root)
entry.pack()

button_1 = tk.Button(root, text="Get Value 1", command=get_value_1)
button_1.pack()

button_2 = tk.Button(root, text="Get Value 2", command=get_value_2)
button_2.pack()

button_3 = tk.Button(root, text="Get Value 3", command=get_value_3)
button_3.pack()

root.mainloop()
