Keep in mind that the above basically takes the task off the list of runnables for 0.2 seconds, so it sits doing nothing and doesn't interfere with other tasks running. In the case where you're doing actual computation, you want to yield (await) much more often than 0.2 sec, so other tasks can stay responsive. This is cooperative multitasking, where each task has to be nice to the others, in contrast with preemptive multitasking where the task switches happen behind the scenes. -- https://mail.python.org/mailman/listinfo/python-list
