What is the appropriate use of asynchronous operations compared to multithreading?

Asynchronous operations in Python (for example, using asyncio) are better suited for tasks that involve many input/output (I/O) operations, such as network requests, file handling, or database interactions, where the program can wait for a response without blocking the main thread.

Multithreading, on the other hand, is effective for tasks that can run in parallel and are not heavily dependent on the GIL (Global Interpreter Lock), such as working with external C libraries or parallel data processing.

Example: if you need to make many network requests, an asynchronous approach allows you to run them concurrently without creating a large number of threads, which saves resources and increases performance.
