This pauses the generator when there are enough active tasks, and lets the event loop clean up finished tasks. Note, for older python versions, replace create_task with ensure_future. Share Improve this answer Follow answered Jun 23, 2021 at 15:42 benjimin 4,52411 gold badge3434 silver ...
An event loop of tasks. The event loop's job is to call tasks every time they are ready and coordinate all that effort into one single working machine. The IO part of the event loop is built upon a single crucial function called select. Select is a blocking function, implemented by the...
asyncio.get_event_loop() 获取当前事件循环。 如果当前 OS 线程没有设置当前事件循环并且set_event_loop()还没有被调用,asyncio 将创建一个新的事件循环并将其设置为当前循环。 由于此函数具有相当复杂的行为(特别是在使用了自定义事件循环策略的时候),更推荐在协程和回调中使用get_running_loop()函数而非get_ev...
