如何在运行websockets服务器的同时运行另一个函数？

import asyncio
import threading
import websockets

# WebSockets服务器
async def websocket_server(websocket, path):
    # 处理WebSockets连接
    await websocket.send("Hello from WebSockets server!")
    async for message in websocket:
        # 处理接收到的消息
        await websocket.send("Received: " + message)

# 另一个函数
def another_function():
    # 执行另一个任务
    print("Running another function...")

# 多线程
def run_in_thread():
    # 启动WebSockets服务器
    start_server = websockets.serve(websocket_server, 'localhost', 8000)
    asyncio.get_event_loop().run_until_complete(start_server)
    asyncio.get_event_loop().run_forever()

# 异步编程
async def run_async():
    # 启动WebSockets服务器
    start_server = websockets.serve(websocket_server, 'localhost', 8000)
    asyncio.ensure_future(start_server)
    while True:
        # 执行另一个任务
        another_function()
        await asyncio.sleep(1)

# 启动多线程
thread = threading.Thread(target=run_in_thread)
thread.start()

# 启动异步编程
asyncio.run(run_async())
