When should you use asyncio.Lock over threading.Lock?
This tests cooperative multitasking knowledge: asyncio.Lock yields to the event loop via await, while threading.Lock blocks the OS thread and freezes the loop. A red flag is claiming threading.Lock works because locks are universal.
This tests your grasp of Python concurrency models: asyncio.Lock is designed for single-threaded cooperative multitasking and uses await to yield control back to the event loop, letting other tasks run. threading.Lock blocks the native OS thread, which freezes the entire event loop and every task on it. A solid answer names a concrete scenario like guarding a shared mutable counter across tasks during an awaitable database write.
