Create a script that keeps track of the goods the user placed into their cart and totals it at the end. The three functions should be used - def_home(): - the home menu, def_goods(): - displays goods that can be purchased, def_item(): - keeps track of the count and cost of goods to total them and display when the script is ended, and more if needed..

** strip the string input/user input. consider for upper/lower case inputs. no global variables. function must return the option selected.**
