Help with lists and class objects

[Marbelous]

That's the beauty of over-riding the magic methods (also called "dunders" for double underscores). You don't have to do anything else. Any time your object gets printed, __str__ will get called and whatever you defined in it will be printed. See how when I "print(thing1)" it just works. Pretty useful!

class Items():
    """ Base class of Player's items. """
    
    inventory = [] # Static class attribute to hold all items.  Note that it's IN the class.
    
    def list_items(): # Static method to print the items in the static inventory. 
        for i in Items.inventory:
            print(i)

    def __init__(self, name, desc):
        """ Constructor for the Items class. """

        self.name = name
        self.description = desc
        self.attack = 10
        self.defense = 10
        self.value = 25
        Items.inventory.append(self)

    def __str__(self):
        return self.name

    def show_item_info(self):
        print("-----------------------------------------")
        print(f"Item name: {self.name}")
        print(self.description)
        print(f"Attack: {self.attack} / Defense: {self.defense}")
        print("-----------------------------------------")

# Instantiate a couple items:
thing1 = Items("Iron Sword", "A rusty iron short sword that badly needs a blacksmith.")
thing2 = Items("Wooden Shield", "A tattered, oak shield that has seen better days but does the job.")

# Print some output about the Items:
print(thing1)  # Just USE it.  Works since you over-rode __str__ "magic method"!

thing2.show_item_info()

Items.list_items()

I guess I should have mentioned that overriding __str__() and __repr__() is not the only way to print stuff from a class instance. As you see in my code I also added a fancy, multi-line show_item_info() method that simply prints lines that happen to contain several attributes from the class. Of course you can combine the techniques too. You could make a nice printout of all the items in the inventory as a pretty 2D table but leave out the descriptions...
