How does async/await improve performance in Python 3?

How does async/await improve performance in Python 3?

Async/await allows for non-blocking code execution, enabling better performance in I/O-bound tasks by allowing other tasks to run while waiting.

Can you give me an example of how to use async/await in a Python function?

Sure! Here's a simple example:

import asyncio

async def fetch_data():
    await asyncio.sleep(1)  # Simulates a network call
    return 'Data fetched'

async def main():
    result = await fetch_data()
    print(result)

asyncio.run(main())

What are the limitations of using async/await in Python?

Some limitations include complexity in debugging, not being suitable for CPU-bound tasks, and requiring an event loop.

Is async/await supported in Python 2?

No, async/await is not supported in Python 2. It was introduced in Python 3.5.
