Understanding Python Requests Async Await

If you are into web development, then you are probably familiar with Python Requests library. It is one of the most popular and widely used libraries for making HTTP requests in Python. However, when it comes to making asynchronous requests, the traditional way of using Requests library might not be the best approach. That's where Python Requests Async Await comes in.

What is Async Await?

Async Await is a new syntax introduced in Python 3.5 that makes writing asynchronous code much easier and more readable. It is based on the concept of coroutines and allows you to write asynchronous code in a synchronous style. With Async Await, you can write non-blocking code that runs concurrently and doesn't block the main event loop.

How to use Python Requests Async Await?

Using Python Requests Async Await is quite simple. You can use the "aiohttp" library, which is an asynchronous HTTP client/server library for Python. Here's an example:

import aiohttp
import asyncio

async def fetch(session, url):
    async with session.get(url) as response:
        return await response.text()

async def main():
    async with aiohttp.ClientSession() as session:
        html = await fetch(session, '')

loop = asyncio.get_event_loop()

In this example, we define an asynchronous function "fetch" that takes in a session object and a URL. In this function, we use the "async with" statement to make an asynchronous HTTP request using the session object. We then use the "await" keyword to wait for the response and return the text content of the response.

We then define another asynchronous function "main" that creates a new instance of the "ClientSession" class using the "async with" statement. We then call the "fetch" function with the session object and the URL and use the "await" keyword to wait for the response. Finally, we print the HTML content of the response.

Finally, we create an event loop using the "asyncio.get_event_loop()" function and run the "main" function using the "loop.run_until_complete()" method.


Python Requests Async Await is a powerful way to make asynchronous HTTP requests in Python. With the help of the "aiohttp" library and Async Await syntax, you can write non-blocking code that runs concurrently and doesn't block the main event loop. So, next time you need to make asynchronous HTTP requests, be sure to give Python Requests Async Await a try.
