这是 GPT4 的回答，考察的应该是：asyncio.to_thread 这个知识点。
You can use asyncio.to_thread() to run the synchronous function sync_f() in a separate thread, allowing it to run concurrently with the asynchronous function async_g(). Here's how you can achieve this:
python
Copy
import asyncio
import threading
import time
def sync_f(a=None):
lock = threading.Lock()
lock.acquire(blocking=False)
lock.acquire(timeout=3)
return 2
async def async_g(a=None):
await asyncio.sleep(3)
return 1
async def main():
# Run sync_f() in a separate thread and async_g() concurrently
sync_f_task = asyncio.to_thread(sync_f)
async_g_task = async_g()
results = await asyncio.gather(sync_f_task, async_g_task)
print(results)
if __name__ == "__main__":
asyncio.run(main())
This code will run both sync_f() and async_g() concurrently, and print their results once both are completed.
