In which cases is it better to use asynchronous operations?

Asynchronous operations are better used when you need to perform tasks that may take a long time without blocking the main thread. For example:

• Network requests (loading data from a server).
• Working with files (reading/writing large volumes).
• Interacting with a database.
• Performing long computations, if they can be offloaded to a separate thread.

In Python, this is often done using asyncio, which allows writing asynchronous code with async and await.

Example:

import asyncio

async def fetch_data():
    print('Starting download')
    await asyncio.sleep(2)  # simulate delay
    print('Data loaded')

async def main():
    await fetch_data()

asyncio.run(main())

This approach improves application responsiveness and resource utilization.
