Description

Hi, this my attempt to build a script for an e-commerce web app using Flask. ### Templates:

  • The index template serves as the catalog for the shop’s products.
  • Cart template deal with user’s transactions
  • Payment template
  • The products template displays all products .

other files:

  • Database.
  • helpers– functions that help.
  • App– main script
