def replace_label_text():
    label.config(text="新标签")

root = tk.Tk()

# 创建初始标签
label = tk.Label(root, text="旧标签")
label.pack()

# 创建按钮来替换标签文本
button = tk.Button(root, text="点击替换标签", command=replace_label_text)
button.pack()

root.mainloop()

import tkinter as tk

def replace_label():
    global label
    label.destroy()  # 销毁原标签
    label = tk.Label(root, text="新标签")  # 创建新标签
    label.pack()

root = tk.Tk()

# 创建初始标签
label = tk.Label(root, text="旧标签")
label.pack()

# 创建按钮来替换整个标签
button = tk.Button(root, text="点击替换标签", command=replace_label)
button.pack()

root.mainloop()
