What is asyncio in Python and how does it work?

Asyncio is a library in Python used for writing concurrent code using the async/await syntax. It allows you to run multiple tasks at the same time without blocking the main thread.

Can you explain the event loop in asyncio?

The event loop is the core of asyncio. It manages the execution of asynchronous tasks, handling events and scheduling them to run when their resources are available.

What are coroutines and how do they differ from regular functions?

Coroutines are special functions defined with 'async def' that can pause and resume their execution. Unlike regular functions, they allow for non-blocking operations.

How do I handle exceptions in asyncio?

You can handle exceptions in asyncio using try/except blocks within your coroutines. This allows you to catch and manage errors that occur during asynchronous operations.

Can you give me an example of using asyncio with HTTP requests?

Sure! You can use the 'aiohttp' library with asyncio to make asynchronous HTTP requests, allowing you to fetch data from multiple URLs concurrently.
