⚡ Python Async & Await Basics

Async programming helps your program run multiple things at the same time without waiting around. Python uses async and await keywords to make this easy.

🧩 What’s Async?

It lets your code pause and wait for tasks (like network calls) without freezing the whole program. This is great for speeding up I/O-bound tasks.

🖥️ Example 1: Basic Async Function

This example defines a simple async function that "waits" for 1 second before printing.

🔍 Key Concepts

async def: Declares an async function.
await: Pauses until the awaited task finishes.
asyncio.run(): Runs the main async function.
Useful for I/O-bound and high-latency tasks (network, files, etc.)

🖥️ Example 2: Running Multiple Async Tasks

Here, two async tasks run “simultaneously” with asyncio.gather().

💡 Pro Tip: Use async/await to avoid blocking your app during slow I/O operations like network requests or file reads.
