class Person: def __init__(self, name, age): self.name = name self.age = age class PersonFactory: def create_batch(self, num_people): people = [] for i in range(num_people): person = Person(f"Person {i}", i) people.append(person) return people factory = PersonFactory() people = factory.create_batch(5) for person in people: print(f"{person.name} is {person.age} years old")In this example, we define a simple Person class with two properties: name and age. We then define a PersonFactory class with a create_batch method that creates a batch of Person instances based on the input parameter num_people. We then create an instance of the factory and use it to create a batch of 5 people. Finally, we iterate over the list of people and print out their name and age. The package library used in this example is the standard Python library, which provides built-in support for creating classes, functions and objects.
