4:30 PM – Python OOP – Roland

Today We Did

1. Finished LibrarySystem Project
   • Fixed bugs in getting info from books and checking whether a books publishing year was before 2000
   • Find Book By ID
   • Super Secret Password mechanism to exit the program
2. Reviewed How Dictionaries Worked
   1. Dictionaries are like lists except we don’t get items by their index, we use a special magic key that is connected to a value (which is usually an object)
      1. dictionary[key] = value

Homework

We are going to be starting the SuperMarket project!!!

Before next class please create two files:

One file should be named “shopping_cart_main.py” and the other file should be named “grocery_item.py”

In the grocery_item.py file, create a class called GroceryItem

Make this with this class we can store the attributes: name, price, frozen_food and make it so we can initialize them in the constructor (__init__)

(Feel free to add any more attributes or methods you want in the GroceryItem class but that should be the bare minimum)

Import this GroceryItem class from grocery_item.py into shopping_cart_main.py at the top of the file using import
