Is Requests Async Python?

Yes, requests can be async in Python. By default, requests module sends and waits for the response synchronously which means it will block the entire program until it has received a response from the server. However, this may not be ideal for certain cases especially when dealing with a large number of requests or when you want to perform other tasks while waiting for the response.

In such cases, using the async version of requests can help to improve the performance of your program. The async version of requests is called httpx.

How to use httpx?

First, you need to install it using pip:

pip install httpx

Then, you need to create an async function and use the async version of httpx's request method:

import httpx

async def get_data_async():
    async with httpx.AsyncClient() as client:
        response = await client.get('')
        return response.text

The above code snippet creates an async function called get_data_async() that sends an asynchronous GET request to and returns the response as text.

The key difference between using the sync version of requests and async version of httpx is the use of async with httpx.AsyncClient() as client: instead of just using requests.get().

Advantages of using async httpx

  • Improved performance: async functions allow other tasks to be executed while waiting for a response
  • Better scalability: async functions can handle a large number of requests without blocking the entire program
  • Easier error handling: async functions allow you to handle errors more easily using try/except blocks

Other ways to perform async requests in Python

Aside from using httpx, there are other ways to perform async requests in Python such as using asyncio, aiohttp, or curio. However, these options may require more setup and configuration compared to httpx.
