What are some tips for using the Python asyncio library?

Here are a few tips for using the asyncio library in Python:

1. Use async and await keywords to define asynchronous functions.
2. Utilize asyncio.run() to execute your main coroutine.
3. Take advantage of asyncio.gather() to run multiple coroutines concurrently.
4. Be mindful of blocking calls; use non-blocking alternatives whenever possible.

Can you explain how asyncio.gather() works?

Certainly! asyncio.gather() is used to run multiple asynchronous tasks concurrently. It takes in multiple awaitable objects (like coroutines) and returns a single future that resolves when all the tasks are completed. You can also specify the order of results by passing the tasks in the desired order.

What are some common mistakes to avoid with asyncio?

Common mistakes include:

1. Forgetting to use await when calling asynchronous functions.
2. Blocking the event loop with synchronous code.
3. Not handling exceptions in coroutines, which can lead to unhandled errors.

How can I debug asyncio code effectively?

To debug asyncio code, you can:

1. Use logging to track coroutine execution.
2. Utilize asyncio.run() with a debugger.
3. Check for unawaited coroutines using asyncio.all_tasks().
