Difference between blocking and non-blocking tasks in python

example.py

import time
import asyncio


async def my_blocking_task(task_id):
    print(f"running blocking {task_id}")
    time.sleep(2)  # faking cpu task


async def my_nonblocking_task(task_id):
    print(f"running nonblocking {task_id}")
    await asyncio.sleep(2)


async def run_all(my_task):
    loop = asyncio.get_running_loop()
    tasks = [loop.create_task(my_task(task_id)) for task_id in range(3)]
    await asyncio.gather(*tasks)


if __name__ == "__main__":
    start = time.time()
    asyncio.run(run_all(my_blocking_task))
    end = time.time()
    print(f"Blocking: {end - start}s")

    start = time.time()
    asyncio.run(run_all(my_nonblocking_task))
    end = time.time()
    print(f"NonBlocking: {end - start}s")
