Can you list components and objects that implement asynchrony in Python?

Asynchronous programming in Python is implemented using several key components:

• The keywords async and await for declaring and calling asynchronous functions (coroutines).
• The asyncio module — the main framework for writing asynchronous code, containing the event loop, tasks, coroutines, and synchronizers.
• Future objects — representing the result of an asynchronous operation that will be available in the future.
• Classes and functions for working with asynchronous input/output, such as asyncio.StreamReader and asyncio.StreamWriter.
• Asynchronous generators and context managers for convenient handling of data streams and resources.

An example of a simple asynchronous function using asyncio:

import asyncio

async def say_hello():
    await asyncio.sleep(1)
    print("Hello after 1 second")

async def main():
    await say_hello()

asyncio.run(main())

Thus, asynchronous programming in Python allows writing non-blocking code that efficiently utilizes resources when working with input/output.
