Making HTTP Requests and Handling Responses with Python

In today's connected world, interacting with web services is an essential part of many applications. Python provides several excellent libraries that simplify the process of making HTTP requests and handling the resulting responses. In this article, we will explore some of these libraries and learn how to utilize them effectively.

Introduction to HTTP Requests

HTTP (Hypertext Transfer Protocol) is the foundation of communication on the World Wide Web. It enables clients (like web browsers) to request resources from servers and receive responses containing the requested data.

To make an HTTP request in Python, we need a library that provides the necessary functionality. The most popular libraries for this purpose are httplib, urllib, httplib2, http.client, requests, and httpie.

In this article, we will focus on the widely-used requests library, which provides a simple and elegant API for making HTTP requests.

Installing the requests Library

To get started, we need to install the requests library if it is not already installed. Open your command line interface (CLI) and run the following command:

pip install requests

This command will install the latest version of the requests library from the Python Package Index (PyPI).

Making HTTP GET Requests

The most common type of HTTP request is the GET request, which is used to retrieve data from a server. Let's see how we can make a GET request using the requests library:

import requests

response = requests.get('')

In this example, we make a GET request to the URL using the get method provided by requests. The response object contains the server's response to our request.

Handling the Response

Once we have made an HTTP request and received a response, we will typically need to process the data somehow. The response object provides various methods and attributes to access the response data.

Retrieving the Response Content

To access the content of the response, we can use the content attribute:

content = response.content

The content attribute returns the response content as bytes. If we want to convert it to a string, we can use the text attribute instead:

text = response.text

Retrieving the Response Status Code

The status code is a three-digit number that informs us about the status of our request. It indicates whether the request was successful, encountered an error, or requires further action.

To access the status code of the response, we can use the status_code attribute:

status_code = response.status_code

Handling Errors

In some cases, the server may respond with an error status code. To handle such errors gracefully, we can use the raise_for_status method, which raises an exception if an HTTP error occurred:


By using this method, we can ensure that our program does not proceed further if the server returns an error.


In this article, we explored the requests library and learned how to make HTTP requests and handle the resulting responses. We saw how to install the library, make GET requests, and access the response's content and status code.

Using the requests library, Python developers can easily interact with web services and retrieve data from the internet. This functionality is essential for building modern applications that rely on external APIs and services. With some practice and experimentation, you will become proficient in making HTTP requests and handling responses in Python.
