+Grocery List Creator Python program
+
+Created by Joseph C. Richardson
+
 This is a full functional grocery list Python program example to add to my Python book.
 Feel free to copy this Python program example if you like. See what you can do with it.
-As time rolls on, I will make this an actual, working program, which the user can place
-the price of a grocery list item, while it keeps track of what you will be spending at the
-store. The user will also be able to clear the list items or clear just one single list item,
-while the price part of the program will work as addition and subtraction of list pricing,
-via items added or removed from the shopping list. You are all welcome to copy this
-program and make it do and be anything you like. Maybe try and create the list, such as
-what I want to make it do down the road. Please enjoy.
+Please enjoy.
