•

Python CLASSMETHOD decorator clearly explained !!!

Imagine you are working as a backend engineer for a company whose software is used by various retail outlets. You've been tasked to create a class 'Product' which helps create a new product by taking in name, price & quantity_in_stock. You do a simple harmless implementation ↓

Your firm now get's a new retail outlet who want to use your software but need to create the product not based on name, price & quantity_in_stock but a product_code Your 'Product' class looks at your like this

'classmethod' decorator to the rescue which helps create alternatie constructors i.e. initialize a class in more ways thann one Modified 'Product' class which takes cls & product_code & creates instance of Product `cls` refers to the Product class & is just a naming convention

Here's how the `Product` class now performs & can create products in more ways. Now, no matter how many retail outlets your sales team manage to onboard you know how to effectively cater to their product creation requirements :)
