What are advanced getters and setters in Python?

Advanced getters and setters in Python allow you to control access to class attributes, enabling validation and computed properties.

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

Sure! Here's a simple example:

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

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

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

What happens if I try to set an empty name?

If you try to set an empty name, it will raise a ValueError with the message 'Name cannot be empty'.

Are there any performance considerations with using properties?

Using properties can introduce a slight overhead due to the method calls, but it's usually negligible compared to the benefits of encapsulation.
