How do I implement the Factory Pattern in my code?

The Factory Pattern is a creational design pattern that provides an interface for creating objects in a superclass, but allows subclasses to alter the type of objects that will be created. Would you like a code example?

Yes, please provide a code example in Python.

Sure! Here's a simple example:

class Car:
    def drive(self):
        return "Driving a car"

class Truck:
    def drive(self):
        return "Driving a truck"

class VehicleFactory:
    @staticmethod
    def create_vehicle(vehicle_type):
        if vehicle_type == 'car':
            return Car()
        elif vehicle_type == 'truck':
            return Truck()
        else:
            raise ValueError('Unknown vehicle type')

# Usage
vehicle = VehicleFactory.create_vehicle('car')
print(vehicle.drive())  # Output: Driving a car

What are the benefits of using the Factory Pattern?

The Factory Pattern promotes loose coupling in your code, making it easier to manage and extend. It also encapsulates the object creation process, allowing for more flexibility in changing the types of objects created.
