asyncio — Asynchronous I/O — Python 3.12.6 documentationasyncio is a library to write concurrent code using the async/await syntax. asyncio is used as a foundation for multiple Python asynchronous frameworks that provide high-performance network and web-servers, database connection libraries, distributed task queues, etc.
The async with statement will wait for all tasks in the group to finish. While waiting, new tasks may still be added to the group (for example, by passing tg into one of the coroutines and calling tg.create_task() in that coroutine). Once the last task has finished and the async with block is exited, no new tasks may be added to the group.. The first time any of the tasks belonging to the ...
Future objects are used to bridge low-level callback-based code with high-level async/await code.. Future Functions¶ asyncio. isfuture (obj) ¶ Return True if obj is either of:. an instance of asyncio.Future,. an instance of asyncio.Task,. a Future-like object with a _asyncio_future_blocking attribute.
asyncio synchronization primitives are designed to be similar to those of the threading module with two important caveats:. asyncio primitives are not thread-safe, therefore they should not be used for OS thread synchronization (use threading for that);. methods of these synchronization primitives do not accept the timeout argument; use the asyncio.wait_for() function to perform operations ...
pid ¶. Process identification number (PID). Note that for processes created by the create_subprocess_shell() function, this attribute is the PID of the spawned shell.. returncode ¶. Return code of the process when it exits. A None value indicates that the process has not terminated yet.. A negative value -N indicates that the child was terminated by signal N (POSIX only).

Asynchronous Python: A Beginner’s Guide to asyncioIn this article, we explored the basics of asynchronous programming in Python using the asyncio module. We learned how to mark functions as asynchronous, use the await keyword to wait for asynchronous tasks, and coordinate multiple tasks using asyncio.gather.

python - How does asyncio actually work? - Stack OverflowIt allows you to write single-threaded asynchronous code and implement concurrency in Python. Basically, asyncio provides an event loop for asynchronous programming. For example, if we need to make requests without blocking the main thread, we can use the asyncio library.
