What are some real-world uses of asynchronous code in Python?

Asynchronous code in Python is often used in web development, data processing, and network applications. For example, frameworks like FastAPI and Tornado utilize async features to handle multiple requests simultaneously, improving performance.

Can you give me an example of how it's used in web development?

Sure! In web development, asynchronous code allows a server to handle multiple client requests at the same time without blocking. For instance, using FastAPI, you can define endpoints that process requests concurrently, making your application more responsive.

What about in data processing?

In data processing, asynchronous code can be used to fetch data from multiple sources simultaneously. For example, you can use the asyncio library to run multiple I/O-bound tasks, like reading from APIs or databases, in parallel, which speeds up the overall data retrieval process.

Are there any downsides to using asynchronous code?

Yes, while asynchronous code can improve performance, it can also introduce complexity. Debugging async code can be more challenging, and not all libraries support async operations, which may lead to compatibility issues.
