Website with Payment Gateway Integration in Python

An e-com website with payment integration that will have the functionality for users to buy courses online. It is NOT an LMS platform. Only payment and invoice will be processed.

A simple platform for purchasing the course, and will direct them to their account where they can download the invoice/receipt and check the course details of the course they purchased. The receipt/invoice should also be mailed to them. Python should be used for back-end development.
