Kuidas suhtleb Event Loop mehhanism Pythonis asyncio teegis korutinitega?

In the Python asyncio library, the Event Loop mechanism is responsible for managing the execution of coroutines — special functions that can suspend their execution, allowing other tasks to run concurrently in a single thread.

The Event Loop constantly checks which coroutines are ready to run (for example, when an I/O operation is completed) and resumes them. When a coroutine encounters the await keyword, it pauses, freeing the Event Loop to run other coroutines. When the awaited event occurs (for example, data is read from the network), the Event Loop resumes the execution of the corresponding coroutine.

Example:

import asyncio

async def say_hello():
    print('Hello')
    await asyncio.sleep(1)  # pauses the coroutine for 1 second
    print('World')

asyncio.run(say_hello())

Here, the Event Loop manages the pause of asyncio.sleep, allowing other tasks to execute during this time.
