title: Can an asyncio event loop run in the background without suspending the Python interpreter?
body: <p>The documentation for asyncio gives two examples for how to print "Hello World" every two seconds:
  <a href="https://docs.python.org/3/library/asyncio-eventloop.html#asyncio-hello-world-callback">https://docs.python.org/3/library/asyncio-eventloop.html#asyncio-hello-world-callback</a>
  <a href="https://docs.python.org/3/library/asyncio-task.html#asyncio-hello-world-coroutine">https://docs.python.org/3/library/asyncio-task.html#asyncio-hello-world-coroutine</a></p>
  
  <p>I can run those from the interpreter, but if I do I lose access to the interpreter. Can an asyncio event loop be run in the background, so that I can keep typing commands at the interpreter?</p>
