How to Pythonically Implement Getters and Setters?

Pythonic Practice for Getters and Setters

When working with getter and setter methods in Python, it's crucial to adopt a Pythonic approach that aligns with the language's best practices. Instead of using explicit get_property() and set_property() methods, which require manual implementation:

def set_property(property, value):  
def get_property(property):  

Or directly setting and retrieving attributes via object properties:

object.property = value  
value = object.property

The preferred Pythonic method utilizes property decorators to define getters and setters. This technique provides a concise and intuitive interface for accessing instance variables.

Property Decorators:

class C(object):
    def __init__(self):
        self._x = None

    @property
    def x(self):
        """I'm the 'x' property."""
        print("getter of x called")
        return self._x

    @x.setter
    def x(self, value):
        print("setter of x called")
        self._x = value

    @x.deleter
    def x(self):
        print("deleter of x called")
        del self._x

Usage:

Create an instance of the class:

c = C()

Set the property:

c.x = 'foo'  # setter called

Retrieve the property:

foo = c.x    # getter called

Delete the property:

del c.x      # deleter called

By employing Python's property decorators, you can achieve getter and setter functionality with a more Pythonic and elegant syntax, maintaining code clarity and simplifying property management.
