Python Script [ Log-In ] in one website using credentials.

HI!
Looking for one experienced Python & Web Scraping developer to do a small script using requests,bs4……. (please not drivers) to log-in into a website.

Script is so basic:
Need to get one mail and one password form on .txt or .json file and then put this fields in the log-in form in the website.
Here is the link: https://www.courir.es/on/demandware.store/Sites-Courir-ES-Site/es_ES/Login-Show

Clean code is appreciated ! Reason i prefer to not use drivers is because i want a fast script and as u will know fast speeds are not possible with chrome driver or other drivers…

Looking the best profile, we could to do more things on the future for sure.
Thanks and happy holidays.
