concurrent.futures模块 Theconcurrent.futuresmodule packs some really great stuff for writing async codes easily. My favorites are theThreadPoolExecutorand theProcessPoolExecutor. These executors maintain a pool of threads or processes. We submit our tasks to the pool and it runs the tasks in availab...

1. 使用`async`和`await`定义协程函数: 复制 importasyncio async def my_coroutine(): await asyncio.sleep(1)print("Coroutine executed")asyncio.run(my_coroutine()) 1. 2. 3. 4. 5. 6. 7. 8. 9. 2. 使用`asyncio.create_task()`并发运行多个协程: ...
asyncio并发wait python async await 并行 一些随笔 理解一些名词(简单的说,具体定义可百度) 并发(concurrency):同一时间段内执行多个任务,但是在同一时刻你只可以执行一个任务。 并行(parallellism):同一时刻执行多个任务。 同步异步关注的是消息通信机制 同步(Synchronous):调用方必须等待这个调用返回结果才能继续执行。
