Since we don't store a reference to the background task we create, the garbage collector may destroy the task before it finishes. To avoid that, we need to store a reference to the task until it finishes. The official documentation recommends the following pattern:
python bg_tasks = set()
async def main(): t = asyncio.create_task(child())
# hold the reference to the task # in a global set bg_tasks.add(t)
# automatically remove the task # from the set when it's done t.add_done_callback(bg_tasks.discard)
