XSS example using python requests and rendered html code

I am currently working on python code that demonstrates or tests a XSS vulnerability. I have a django project site, that I am using python-requests to log into the site, and then send some post or get requests to the server to exploit this vulnerability. What I have learned recently is that the python requests module does not actually render the HTML text or said differently it does not process the <script> tags. That is, if a field is vulnerable to a XSS attack, and you inject the <script>something</script> that does not get rendered in the response object, and so the attack does not actually work. I need someone to show me a workable example of how I can actually use python to interact a with a django site and then exploit a xss vulnerability so that javascript execute. I am working on a practical example to steal a cookie using a javascript call to a local webserver I am running.
