基本异步函数

import asyncio

async def fetch_data():
   await asyncio.sleep(1)
   return "数据"

async def main():
   result = await fetch_data()
   print(result)

asyncio.run(main())

并发执行

async def main():
   tasks = [fetch_data() for _ in range(3)]
   results = await asyncio.gather(*tasks)
   print(results)
