💡 Concept ✅ Quick Revision 🐍 Python

Answer

asyncio is Python’s standard library for event-loop-based asynchronous I/O. • It provides coroutines, tasks, synchronization primitives, subprocess support, and networking APIs. • asyncio.run() is the common entry point for a top-level coroutine. • It is designed for cooperative concurrency rather than automatic parallel execution.

💡 Simple Example

import asyncio

async def main():
    print('asyncio')

asyncio.run(main())

Output

asyncio
