When should I use getters and setters in Python?

Getters and setters are used to control access to class attributes. They allow you to add validation or processing when getting or setting a value.

Can you give me an example of how to implement them?

Sure! Here's a simple example:

class Person:
    def __init__(self, name):
        self._name = name  # private attribute

    @property
    def name(self):  # getter
        return self._name

    @name.setter
    def name(self, value):  # setter
        if not value:
            raise ValueError('Name cannot be empty')
        self._name = value

What are the benefits of using them instead of direct access?

Using getters and setters allows for encapsulation, meaning you can change the internal implementation without affecting external code. It also enables validation and additional logic when accessing or modifying attributes.

Are there any downsides to using them?

Yes, using getters and setters can add complexity and verbosity to your code. In Python, it's often more idiomatic to access attributes directly unless you need the additional control.
