One system runs many processes (multiprocessing concurrency).In turn, a process may run many threads, often many thousands of threads. Recall that one thread may run many coroutines, in fact, many thousands of coroutines. The difference is the unit of concurrency that is blocked: threads vs coroutines (asyncio tasks). asyncio.sleep(): blocks the current coroutine (asyncio task).time.sleep(): blocks the current thread.The important difference between asyncio.sleep() and time.sleep() is that asyncio.sleep() is non-blocking and time.sleep() is blocking. Like asyncio.sleep(), the time.sleep() takes a time in seconds and blocks the current unit of computation. Now that we know what the sleep() is, let’s look at how to use it. Sleep() always suspends the current task, allowing other tasks to run. This means while one coroutine or task is sleeping, other tasks and coroutines can execute. It is referred to as a “ non-blocking“, which means it does not block the current thread from executing. Sleep means that the current execution is paused or suspended (blocked) for a fixed time. The asyncio.sleep() function provides a non-blocking sleep operation. Sleep is an important part of asyncio programs and is provided by the sleep() function. Example of Not Awaiting asyncio.sleep().Example of Periodic Task with asyncio.sleep().Example of asyncio.sleep(0) to Let Another Task Run.
