Using Session object with Python Requests

The Requests Session object allows you to persist specific parameters across requests to the same site. To get the Session object in Python Requests, you need to call the requests.Session() method. The Session object can store such parameters as cookies and HTTP headers. In addition, the Session object allows you to reuse open TCP connections and significantly improve the performance of network requests because you don't have to re-establish a TCP connection each time you send a request. The Session object includes all the methods of the main Requests API. In this Python Requests Session example, we store custom headers and authentication data in a Sessions object.

What is the difference between session and cookies?

A cookie and a session are used to store information. Cookies are only stored on the client machine, and sessions are stored on both the client and the server. The session creates a file in a temporary directory on the server where the registered session variables and their values ​​are stored. This data will be available for all site pages during this visit. Typically, a session ends 30 minutes after the user leaves the site or closes the browser. Cookies are text files that are stored on the client's computer and are designed to track usage. The server script sends a set of cookies to the browser. Cookies are stored locally in the browser for future use.
