如何使用tkinter在两个不同的Progressbars中显示文本？

import tkinter as tk
from tkinter import ttk

def update_progressbar1():
    value = progressbar1['value'] + 10
    progressbar1['value'] = value
    label1.config(text=f'Progress 1: {value}%')
    
def update_progressbar2():
    value = progressbar2['value'] + 5
    progressbar2['value'] = value
    label2.config(text=f'Progress 2: {value}%')

root = tk.Tk()

# 创建两个Progressbar小部件
progressbar1 = ttk.Progressbar(root, orient='horizontal', length=300, mode='determinate')
progressbar1.pack(pady=10)

progressbar2 = ttk.Progressbar(root, orient='horizontal', length=300, mode='determinate')
progressbar2.pack(pady=10)

# 创建两个Label小部件，在Progressbars上方显示文本
label1 = tk.Label(root, text='Progress 1: 0%')
label1.pack()

label2 = tk.Label(root, text='Progress 2: 0%')
label2.pack()

# 创建两个按钮，用于更新Progressbars的值
button1 = tk.Button(root, text='Update Progress 1', command=update_progressbar1)
button1.pack(pady=10)

button2 = tk.Button(root, text='Update Progress 2', command=update_progressbar2)
button2.pack(pady=10)

root.mainloop()
