Add Dictionary to Class

I would like to have my character add items to their inventory from a dictionary, however when I add them it only gives me the 'value' return, not the 'key' as well. I would like to use both for different parts of the game "You are holding 'key', it does 'value' damage" for example.

I think I understand this is adding the dictionaries 'value' because my inventory type is a 'list', but having trouble finding a simple way to add the dictionary items.

Thanks in advance for the help!

from random import randint

class Character:
    # Instantiates each character with personality traits
    def __init__(self, name, health, lives, gender, inventory):
        self.name = name
        self.health = int(health)
        self.lives = int(lives)
        self.gender = gender
        self.inventory = []


inventoryitems = {
    'Breadstick': randint(0,5), 
    'Magic Axe': randint(50,100), 
    'Tiny Fists': randint(0,25),
    'Sword': randint(15,30)
    }

player = Character("Kate", 100, 3, 'female',None)

player.inventory.append(inventoryitems['Magic Axe'])
player.inventory.append(inventoryitems['Breadstick'])
print(player.inventory)

You can use the function items() to iterate over both the keys and the values at the same time:

from random import randint

class Character:
    # Instantiates each character with personality traits
    def __init__(self, name, health, lives, gender, inventory):
        self.name = name
        self.health = int(health)
        self.lives = int(lives)
        self.gender = gender
        self.inventory = []


inventoryitems = {
    'Breadstick': randint(0,5), 
    'Magic Axe': randint(50,100), 
    'Tiny Fists': randint(0,25),
    'Sword': randint(15,30)
}

player = Character("Kate", 100, 3, 'female',None)

# item will be a (key, value) pair
for item in inventoryitems.items():
    player.inventory.append(item)

# or if you only want to add specific items
items_to_add = ['Breadstick', 'Magic Axe']
for item in items_to_add:
    player.inventory.append((item, inventoryitems[item]))

print(player.inventory)

will print e.g.

[('Breadstick', 5), ('Magic Axe', 51), ('Tiny Fists', 21), ('Sword', 17), ('Breadstick', 5), ('Magic Axe', 51)]

Note how adding items twice will not apply new random values to each one, which might not be what you are looking for.

Using dictionary into your class is simple and then you can generate list of item by name using player.inventory.keys(), you also can access item in a very easy and fast way later by doing player.inventory['object_name']

from random import randint

class Character:
    # Instantiates each character with personality traits
    def __init__(self, name, health, lives, gender, inventory):
        self.name = name
        self.health = int(health)
        self.lives = int(lives)
        self.gender = gender
        self.inventory = {}


inventoryitems = {
    'Breadstick': randint(0,5), 
    'Magic Axe': randint(50,100), 
    'Tiny Fists': randint(0,25),
    'Sword': randint(15,30)
    }

player = Character("Kate", 100, 3, 'female',None)

player.inventory['Magic Axe'] = inventoryitems['Magic Axe']
player.inventory['Breadstick'] = inventoryitems['Breadstick']
print(player.inventory)
