asyncio — Asynchronous I/O

threading: Thread-based parallelism.

asyncio synchronization primitives are designed to be similar to those of the threading module with two important caveats:

asyncio.wait_for()

methods of these synchronization primitives do not accept the timeout argument; use the asyncio.wait_for() function to perform operations with timeouts.

asyncio.CancelledError

Pass the barrier. When all the tasks party to the barrier have called this function, they are all unblocked simultaneously.
