asyncio – Asynchronous I/O for Python



This content originally appeared on DEV Community and was authored by MrRobot

asyncio is a standard Python library that provides infrastructure for writing concurrent code using the async/await syntax. It allows developers to manage asynchronous tasks, perform non-blocking I/O operations, and handle multiple tasks simultaneously without threads. asyncio is widely used for building high-performance network servers, web scrapers, and real-time applications where concurrency is crucial. Its event-loop model simplifies managing multiple I/O-bound operations efficiently.

Installation:
asyncio is included in Python’s standard library, so no installation is required.

Example usage:

import asyncio

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

asyncio.run(say_hello())

3 Project Ideas:

  1. Build an asynchronous web scraper that fetches multiple pages concurrently.
  2. Create a chat server that handles multiple client connections efficiently.
  3. Develop a real-time data pipeline for processing incoming data streams.
