How do you gracefully cancel and clean up an asyncio task?
This tests asyncio cooperative cancellation and cleanup. A strong answer covers catching CancelledError at await points, using try/finally or async context managers for cleanup, and re-raising.
This tests deep knowledge of asyncio's cooperative cancellation and safe teardown. A great answer covers catching CancelledError only at await boundaries, using try/finally or async context managers for cleanup, re-raising so the loop knows the task died, and avoiding CPU-bound cleanup that starves the loop. A red flag is suppressing CancelledError blindly, leaving the loop thinking the task is still running, or doing synchronous I/O in cleanup that blocks the thread.
