Explain the concept of Event Loop and its role in asynchronous programming in Python.

The Event Loop is a mechanism that allows asynchronous code to run in Python, especially in the asyncio library. It operates as a loop that constantly checks for tasks ready to be executed (coroutines, callbacks, input-output events) and runs them in sequence.

The role of the Event Loop in asynchronous programming:

• Manages the execution of asynchronous tasks without blocking the main thread.
• Allows efficient resource utilization by waiting for input-output operations (like network requests) to complete and switching between tasks.
• Ensures cooperative multitasking, where tasks voluntarily yield control.

Example of using asyncio and the Event Loop:

import asyncio

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

async def main():
    await asyncio.gather(say_hello(), say_hello())

asyncio.run(main())

Here, the Event Loop runs the say_hello coroutines, switching between them during the asyncio.sleep wait, enabling asynchronous task execution.
