In what situations is it advisable to use classes in Python?

Classes in Python are useful when you need to model objects with state and behavior, combining data and methods in one place. This is convenient for:

• Representing entities from the domain (e.g., user, order, car).
• Encapsulating logic related to these entities.
• Reusing code through inheritance and polymorphism.

Example of using a class:

class User:
    def __init__(self, name, email):
        self.name = name
        self.email = email

    def greet(self):
        print(f"Hello, {self.name}!")

user = User("Ivan", "ivan@example.com")
user.greet()  # Outputs: Hello, Ivan!

If the task is simple and does not require storing state, functions without classes can suffice.
