What are the best practices for using async in Python?
When using async in Python, it's important to use async
and await
keywords properly, avoid blocking calls, and manage exceptions effectively.
Can you explain why blocking calls are a problem?
Blocking calls can halt the execution of your async code, preventing other tasks from running concurrently, which defeats the purpose of async programming.
What libraries should I use for async programming?
Popular libraries for async programming in Python include asyncio
, aiohttp
for HTTP requests, and asyncpg
for PostgreSQL.
How do I handle exceptions in async functions?
You can handle exceptions in async functions using try-except blocks, just like in synchronous code. Make sure to catch specific exceptions.
