How do I debug asynchronous code in Python?

Debugging asynchronous code can be tricky. You can use tools like pdb, logging, or even IDEs with debugging support.

Can you show me an example of using pdb with async code?

Sure! You can set breakpoints in your async functions. Here's a simple example:

import pdb
import asyncio

async def my_async_function():
    pdb.set_trace()  # Set a breakpoint here
    await asyncio.sleep(1)
    print('Hello from async!')

asyncio.run(my_async_function())

What about using logging instead of pdb?

Using logging is a great way to trace execution. You can log messages at different points in your async functions to see the flow.

Can you provide a logging example?

Absolutely! Here's an example:

import logging
import asyncio

logging.basicConfig(level=logging.INFO)

async def my_async_function():
    logging.info('Starting async function')
    await asyncio.sleep(1)
    logging.info('Finished async function')

asyncio.run(my_async_function())
