This coding exercise requires you to complete an implementation of three methods of a class:

1. The __init__  method, which should take an argument, name . It should initialise self.name  to be the argument, and self.items  to be an empty list.
2. The add_item  method, which should append a dictionary representing an item to the store's items  property. The dictionary should have keys name  and price .
3. The stock_price  method, which should add up each item price inside self.items  to come up with a total, and return that.

Good luck!
