Asyncio
asyncio is Python’s standard-library framework for asynchronous programming, built around coroutines, awaitable objects, and event loops.
Python Concurrency with asyncio
A Python library for asynchronous programming that executes coroutines using concurrency mechanisms such as an event loop.
- How it is used
- Handles concurrent I/O workloads such as web requests, database queries, sockets, microservices, and background event processing.
- How deep it goes
- Explains async syntax, coroutines, tasks, cancellation, event loops, non-blocking sockets, pools, queues, and custom loop implementation.
- Examples
- Uses delay tasks, status reporting, echo servers, database batch queries, task runners, process pools, and producer-consumer queues.
- What you can do after
- Build and operate responsive I/O applications with async, await, asyncio.run, tasks, cancellation, queues, and event-loop APIs.
Building LLM Applications with DSPy
asyncio is Python’s standard library for writing concurrent code using the async and await syntax.
- How it is used
- Supports concurrent DSPy program or submodule execution when LM applications spend time waiting on remote work.
- How deep it goes
- Explains coroutines, async/await, and event-loop task management, then demonstrates concurrent waits without detailing scheduler internals.
- Examples
- Uses LM requests as motivation and demonstrates two sleep-based coroutines coordinated with asyncio.gather.
- What you can do after
- Apply it via Python’s asyncio library to coordinate waiting coroutines with async/await, an event loop, and asyncio.gather.
