What are the best practices for using asyncio with threads?

When using asyncio with threads, it's important to keep the following best practices in mind: 1. Use run_in_executor for blocking calls. 2. Avoid mixing asyncio and threading unless necessary. 3. Ensure thread safety when accessing shared resources.

Can you explain how run_in_executor works?

Sure! run_in_executor allows you to run a blocking function in a separate thread or process. It takes an executor as an argument, which can be None for the default executor, and the function to run along with its arguments.

What are some common pitfalls to avoid?

Common pitfalls include: 1. Blocking the event loop with long-running tasks. 2. Not handling exceptions properly in threads. 3. Failing to manage the lifecycle of threads, which can lead to resource leaks.

How can I ensure thread safety in my code?

To ensure thread safety, use synchronization primitives like threading.Lock or asyncio.Lock when accessing shared resources. This prevents race conditions and ensures data integrity.
