QUESTION
This is a follow up question to this question:
Why do most asyncio examples use loop.run_until_complete()?
I'm trying to figure out how asynchronous programming work in python. There's something very basic which I'm still not sure about..
when having this line code: asyncio.ensure_future(someTask)
, will this line ALONE actually enqueue the Future
returned in the default event loop and start the task? Or do I ALSO need to call loop.run_until_complete(someTask)
(or some other kind of run) before that in order to get the event loop up and running?

It will schedule the coroutine, but it won’t run it. You still need to run the loop to do that. You can do that with

Install asyncio-examples
You can use asyncio-examples like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
