ensure_future()的要点是,如果你有一些东西可以是协程或Future(后者包括一个Task的子类,因为那是一个Future),并且您希望能够调用仅在Future上定义的方法(可能唯一有用的示例是cancel())。当它已经是Future(或Task)时,这什么都不做;当它是协程时,它将它包装在Task中。 如果您知道自己有一个协程并且希望对其进行调...
Don’t directly create Task instances: use the ensure_future() function or the BaseEventLoop.create_task() method. 翻译:不要直接创建 Task 实例,应该使用 ensure_future() 函数或 BaseEventLoop.create_task() 方法。 为什么呢?看 create_task 的文档: Third-party event loops can use their own subc...
在 main 函数中,我们使用 asyncio.create_task 将my_coroutine 包装成一个任务,并立即返回一个任务对象。然后,我们使用 await task 来等待任务完成。 create_task 函数与 asyncio 库中其他功能的异同 与asyncio.create_task 类似的功能是 asyncio.ensure_future,它们都可以将一个协程或 Future 对象包装成一个任务。
+1 to the name spawn. I pretty much never use ensure_future because the name makes my code look ambiguous and it has a small amount of overhead compared to loop.create_task. I also don't like the soft edges and interpolation done by ensure_future but that's another topic. My ideal ...
这意味着它被安排在 asyncio 事件循环中,并且无论创建它的协程中发生了什么,它都会执行。这与直接执行协程不同,后者调用者必须等待它完成。... # create a task from a coroutine task = asyncio.create_task(task_coroutine()) 这将做...
