如何让pynput.keyboard作为线程运行？

import threading
from pynput import keyboard

def keyboard_thread():
    def on_press(key):
        # 处理按键按下事件
        print('Key {} pressed.'.format(key))

    def on_release(key):
        # 处理按键释放事件
        print('Key {} released.'.format(key))
        if key == keyboard.Key.esc:
            # 如果按下了ESC键，则停止监听
            return False

    # 创建键盘监听器
    listener = keyboard.Listener(on_press=on_press, on_release=on_release)
    # 启动监听器
    listener.start()

# 创建一个新的线程，并在该线程中运行键盘操作
keyboard_thread = threading.Thread(target=keyboard_thread)
keyboard_thread.start()
