Inventory Check

Before leaving the dungeon, Hoppy needs to make sure he has everything.

Use len() to count items and the in operator to check if something is inside.

Checking Tools

backpack = ["Map", "Compass", "Key"]

# How many items?
count = len(backpack) # 3

# Is "Key" in the backpack?
has_key = "Key" in backpack # True

# Is "Gold" in the backpack?
has_gold = "Gold" in backpack # False

Your Mission

The Bag

We have a list items hidden from you.

Count

Create a variable total that stores the length of items.

Create a variable has_potion that is True if "Potion" is in the list, and False otherwise.

Report

Print total and has_potion.
