Kas sul on küsimusi korutinate kasutamise ja nende omaduste kohta?

Koroutines in Python are implemented using the keywords async and await and allow writing asynchronous code that does not block execution while waiting for input/output operations.

Features of coroutines:

• They do not create new threads, operate in a single thread, and switch during waiting times.
• To start a coroutine, an event loop (asyncio) is needed, which manages their execution.
• Coroutines can improve performance when working with a large number of input/output operations.

Example of a simple coroutine:

import asyncio

async def say_hello():
    print("Hello")
    await asyncio.sleep(1)  # simulation of an asynchronous operation
    print("World")

asyncio.run(say_hello())

If you have questions, for example, about how to correctly use coroutines with blocking code or how to handle exceptions inside coroutines, I can help you understand that.
