Add items with add_item.
Adding items (append)
In this lesson we'll introduce the append list method. append adds an item to a list:
cart = []
cart.append("Apple")
print(cart) # ['Apple']cart.append(...) places a new item at the end of the cart. Since the cart list is mutable, items can be added later. This is the most common use of lists.
Adding multiple items
To add several items to the cart, call append a few times:
cart = []
cart.append("Apple")
cart.append("Bread")
cart.append("Milk")
print(cart) # ['Apple', 'Bread', 'Milk']Each append call adds one more item to the list. The final cart holds all items.
Multiple append calls are the simplest way to fill the cart step by step.
