If you’re a programmer or a developer, chances are you’ve heard of Python. It’s one of the most popular programming languages out there, and it’s easy to see why. Python is versatile, powerful, and relatively easy to learn compared to other programming languages. And when it comes to web scraping, Python’s requests library is an indispensable tool.
But did you know that Python’s requests library also allows you to get and manage cookies? That’s right! Cookies are used all over the internet to track user activity and preferences. They’re also vital to some websites’ functionality, such as e-commerce sites that use cookies to store items in the shopping cart. In this post, we’ll take a closer look at how to use Python requests to get and manage cookies.
Whether you’re a beginner or an experienced programmer, this guide will walk you through the process step-by-step. You’ll learn how to extract cookies from a website, save them to a file, and use them in subsequent requests. We’ll also cover more advanced topics like modifying and deleting cookies. By the end of this post, you’ll have a solid understanding of how to work with cookies in Python requests, giving you even more power in your web scraping endeavors. So, sit back, relax, and let’s dive into the world of Python requests and cookies.

Introduction
Python requests library is used for making HTTP request in Python. It is simple and easy to use library which provides us the ability to send HTTP/1.1 requests using Python. In this article, we will be discussing “Mastering Python Requests: Getting and Managing Cookies”.
What are Cookies?
HTTP Cookies are small files that are stored on a user’s computer by a web browser when browsing a website. These cookies are sent back to the server each time the browser requests a page from the server. They contain information about the user’s preferences, login credentials or session data.
How to Get Cookies Using Python Requests?
In this section, we will talk about how to get cookies from a website using Python requests. This involves sending a GET request to the website and inspecting the response headers for any cookies being set.
Syntax
The syntax for getting cookies using Python requests is as follows:
| Action | Syntax |
|---|---|
| GET Request | r = requests.get(url) |
| Get Cookies | cookies = r.cookies |
How to Manage Cookies Using Python Requests?
In addition to getting cookies, requests also provides functionality for managing cookies. This includes setting, modifying and deleting cookies from the client side.
Syntax
The syntax for managing cookies using Python requests is as follows:
| Action | Syntax |
|---|---|
| Set Cookies | cookies = {‘name’:’value’} |
| Send cookies with Request | r = requests.get(url, cookies=cookies) |
| Modify cookies | r.cookies.set(‘name’, ‘new_value’) |
| Delete cookies | r.cookies.clear() |
Example Use Case: Login to a Website Using Python Requests
Let’s take a look at an example use case of using Python requests to login to a website, and then retrieve data from that website.
Syntax
The syntax for logging in to a website using Python requests is as follows:
| Action | Syntax |
|---|---|
| Set Login Credentials | payload = {‘username’:’your_username’, ‘password’:’your_password’} |
| Login | r = requests.post(login_url, data=payload) |
| Access Protected Resources | r = requests.get(protected_url, cookies=r.cookies) |
Conclusion
Python requests library provides a simple, yet powerful way to interact with websites over HTTP. Whether you need to get or manage cookies, login to websites, or scrape data the web using Python, mastering Python requests is essential skills for any Python developer.
Opinion
I believe that mastering Python requests: Getting and Managing Cookies is an essential skill for any Python developer who wants to work on web-scraping, automation or accessing web-based APIs. With cookies being such a ubiquitous aspect of web applications, it’s important for developers to understand how to work with them effectively in Python, which is where this tutorial comes in handy.

Cookies are small pieces of data that are sent from a website to a user’s web browser. In Python requests, cookies can be used to keep track of user sessions and preferences.
You can get cookies using Python requests by accessing the cookies attribute of the response object. For example:
import requestsresponse = requests.get('https://www.example.com')cookies = response.cookiesprint(cookies)You can set cookies using Python requests by passing a dictionary of cookie key-value pairs to the cookies parameter of the request method. For example:
import requestscookies = {'session_id': '12345'}response = requests.get('https://www.example.com', cookies=cookies)print(response.cookies)You can manage cookies in Python requests by using the session object. The session object automatically stores and sends cookies for subsequent requests. For example:
import requestssession = requests.Session()session.cookies.update({'session_id': '12345'})response1 = session.get('https://www.example.com/page1')response2 = session.get('https://www.example.com/page2')print(response2.cookies)
