Question About Cookies and Python Requests

So I am trying to make a request to a site every 15 seconds or so and about every 15 minutes, I am required to do a captcha again, and that changes my cookie. Would I need to use 2Captcha or something to bypass this captcha or could I randomize part of the cookie or something? I don't know much about cookies, but the cookie that is changing is the Header.

Thanks and have a good day!
