如何为在循环中创建的按钮和标签更新Tkinter参数？

import tkinter as tk

def update_label(index):
    labels[index].config(text="New Text")

root = tk.Tk()
labels = []

for i in range(5):
    label = tk.Label(root, text="Label {}".format(i))
    label.pack()
    labels.append(label)

button = tk.Button(root, text="Update Label", command=lambda: update_label(2))
button.pack()

root.mainloop()
