import NBTHow #Importing NBTHow - assume set up is appropriate

class Merchandise:
    def __init__(self, identify, amount, geared up=False):
        self.identify = identify
        self.amount = amount
        self.geared up = geared up

    def __str__(self):
        return f"Merchandise(identify='{self.identify}', amount={self.amount}, geared up={self.geared up})"

def save_items(gadgets, filename="game_save.json"): #Assume JSON, alter as wanted
    attempt:
        #serialize the record of things
        item_data = []
        for merchandise in gadgets:
            item_data.append({"identify": merchandise.identify, "amount": merchandise.amount, "geared up": merchandise.geared up})
        NBTHow.save_item(item_data, filename)
        print(f"Gadgets saved to {filename}")
    besides Exception as e:
        print(f"Error saving gadgets: {e}")

def load_items(filename="game_save.json"): #Assume JSON, alter as wanted
    attempt:
        item_data = NBTHow.load_item(filename)
        gadgets = []
        for item_dict in item_data:
            merchandise = Merchandise(item_dict["name"], item_dict["quantity"], item_dict["equipped"])
            gadgets.append(merchandise)
        print(f"Gadgets loaded from {filename}")
        return gadgets
    besides FileNotFoundError:
        print("Save file not discovered. Beginning with empty stock.")
        return []
    besides Exception as e:
        print(f"Error loading gadgets: {e}")
        return []

# Instance utilization:
if __name__ == "__main__":
    #Create a pattern record of things
    gadgets = [
        Item("Sword", 1, True),
        Item("Potion", 3),
    ]
    save_items(gadgets) #Saves the preliminary record of things

    loaded_items = load_items()

    #Print out loaded gadgets
    for merchandise in loaded_items:
        print(merchandise)

Walkthrough:

  1. We outline an `Merchandise` class to symbolize every merchandise.
  2. We outline capabilities `save_items()` and `load_items()`.
  3. Inside `save_items()` we serialize the record of `Merchandise` objects right into a Python dictionary, and use the NBTHow library to avoid wasting them as a JSON file.
  4. Inside `load_items()`, we learn the JSON file utilizing `NBTHow`, and re-create our `Merchandise` objects and print their particulars to the console.
