Remember to:

• Ask your Python question, not if you can ask or if there's an expert who can help.
• Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
• Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.

Closes after a period of inactivity, or when you send !close.

Lab12P1b.py reads as follows (item_type commented out for debugging):

from inventory_item import InventoryItem as Inv
from book import Book
from game import Game
from dvd import DVD


def main():
    string_list = []
    for x in range(3):
        # item_type = input('Enter item type (1-Book, 2-Game, 3-DVD): ')
        item_type = "1"
        if item_type == "1":
            Book.get_item_input(x)
            string = Book.__str__
            string_list.append(string)
        else:
            print(f'Input "{item_type}" not valid.')
            x = x-1
    print(f'{string_list[0]}\n{string_list[1]}\n{string_list[2]}')```
book.py reads as follows:
```python
from inventory_item import InventoryItem as Inv


class Book(Inv):
    isbn13 = ""

    def __init__(book, name, count, cost, isbn13):
        super().__init__(book, name, count, cost)
        category = "Book"
        book.__name = name
        book.__count = count
        book.__cost = cost
        book.__category = category
        book.__isbn13 = isbn13

    def get_item_input(book):
        Inv.get_item_input(book)
        # get the isbn
        while True:
            isbn13 = input('Enter the ISBN number: ')
            if len(isbn13) != 13:
                print('ISBN contains 13 characters.')
            elif not isbn13.isdigit():
                print('ISBN number must be all digits.')
            else:
                break
        book.__name = book.item_name
        book.__count = book.count
        book.__cost = book.cost
        book.__isbn13 = isbn13```

problems passing variables between classes?

I feel like there should be a return in InventoryItem.get_item_input() but there isn't one and I'm told the code should be working correctly as-is
