Understanding Factory Pattern in Python

Factory Pattern is a powerful design pattern used to create objects in a systematic manner. 🏭 It helps in encapsulating the creation logic of products, making it easier to manage and extend.

Here’s how you can implement it in Python:

1. Create a Product Interface:
All products created will implement this interface.

   class Product:
       def use(self):
           pass
   

2. Concrete Products:
Define specific products that implement the interface.

   class ConcreteProductA(Product):
       def use(self):
           return "Using Product A"

   class ConcreteProductB(Product):
       def use(self):
           return "Using Product B"
   

3. Factory Class:
This class will handle the creation of the products.

   class Factory:
       @staticmethod
       def create_product(product_type):
           if product_type == 'A':
               return ConcreteProductA()
           elif product_type == 'B':
               return ConcreteProductB()
           else:
               raise ValueError("Unknown product type")
   

4. Using the Factory:
You can easily create products without changing code in your main logic.

   product = Factory.create_product('A')
   print(product.use())  # Output: Using Product A
   

Using the Factory Pattern not only promotes loose coupling but also enhances code readability and maintainability. Give it a try in your next project! 💡✨
