AttributeError: 'int' object has no attribute item

April 26, 2022

The code is:

Offers = [0, 13, 4]
class Shop:
    def __init__(self, item, price, count):
        self.item = item
        self.price = price
        self.count = count

    def CreateNew(self):
        Offers.append(self.item)

Shop.CreateNew(3)

Why does it happen? I’ve been wasting hours searching for an solution, no result.

The error occurs at:

Offers.append(self.item)

>Solution :

Are you thinking something like this?

Offers = [0, 13, 4]
class Shop:
    def __init__(self, item, price, count):
        self.item = item
        self.price = price
        self.count = count

    def CreateNew(self):
        Offers.append(self.item)

# Create new shop object
# Giving None for your price and count, since you don't have them in your example
s = Shop(3, None, None) 
# Call objects method
s.CreateNew()

Or if you want to use CreateNew as a class method you can call without creating a new object, you can do it like this

Offers = [0, 13, 4]
class Shop:
    def __init__(self, item, price=None, count=None):
        self.item = item
        self.price = price
        self.count = count
    
    @classmethod
    def CreateNew(cls, item, price, count):
        c = cls(item, price, count)
        Offers.append(c.items)
        return c


# This adds item to Offers list and returs new shop class for you. 
Shop.CreateNew(3)

But using class methods (or static methods) is unusual in Python. And perhaps a bit advanced in this context. This approach is more common in for example C#.
