Python Requests and HTTP2

Python Requests is a popular library for sending HTTP requests in Python. It simplifies the process of making requests and handling responses, making it a great choice for web scraping or interacting with web APIs.


HTTP2 is the latest version of the HTTP protocol, which is used for communication between a client (such as a web browser) and a server. It is designed to be faster and more efficient than its predecessor, HTTP/1.1.

One of the key features of HTTP2 is its support for multiplexing, which allows multiple requests and responses to be sent over a single connection. This can reduce the amount of time it takes to load a web page, as well as reduce the number of connections a client needs to make to a server.

Python Requests and HTTP2 Support

Python Requests has support for HTTP2, but it is not enabled by default. In order to use HTTP2 with Requests, you need to install the hyper library:

pip install hyper

Once you have installed hyper, you can use Requests as usual, but with the addition of an HTTP20Adapter object:

import requests
from hyper.contrib import HTTP20Adapter

session = requests.Session()
session.mount("https://", HTTP20Adapter())
response = session.get("")

This code creates a new Session object, mounts an HTTP20Adapter to it, and then uses that session to make a GET request to

Other Ways to Use HTTP2 with Python

In addition to using Requests with HTTP2, there are other libraries and frameworks that support this protocol. For example:

  • h2 is a pure-Python implementation of the HTTP2 protocol.
  • aiohttp is an asynchronous HTTP client/server library for Python that supports HTTP2.
  • Twisted is an event-driven networking engine written in Python that supports HTTP2.

Each of these libraries has its own strengths and weaknesses, so it's worth exploring your options to find the one that best fits your needs.
