Property Decorators for Encapsulation

Snippet

Property Decorators for Encapsulation

The @property decorator allows you to define methods that can be accessed like attributes, providing a clean way to implement validation and encapsulation in classes.

snippet.py
python
class Circle:
    def __init__(self, radius):
        self._radius = radius
 
    @property
    def radius(self):
        return self._radius
 
    @radius.setter
    def radius(self, value):
        if value < 0:
            raise ValueError('Radius cannot be negative')
        self._radius = value

Breakdown

@property

Turns a method into a getter for the attribute.

@radius.setter

Defines logic to be executed when the attribute is assigned a value.
