asyncio concurrency

Run many coroutines at once with tasks, gather and TaskGroup; add timeouts, handle failures, coordinate workers with queues — and build an async job scheduler.

You will be able to

• Start concurrent work with asyncio.create_task, gather and TaskGroup and collect results in a predictable order
• Put time limits on slow operations with asyncio.timeout and wait_for
• Handle failures in concurrent code with return_exceptions, try/except inside tasks and ExceptionGroup
• Coordinate producers and a fixed number of workers with asyncio.Queue
• Recognise problems where asyncio is the wrong tool
