How Can I Pythonically Implement Getters and Setters?

What's the Pythonic Way to Use Getters and Setters?

Using getters and setters offers a convenient way to control access to private attributes in Python. Here are some of the commonly used approaches:

Method-Based Approach:

You can create separate getter and setter methods, as shown below:

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

However, this approach is not considered very Pythonic. A more preferred way is to use:

Object Attribute Manipulation:

You can directly assign values to object attributes using the dot notation:

object.property = value  
value = object.property

This approach is easy to use and understand, but it doesn't offer any encapsulation or control over attribute access.

Python Properties:

The most Pythonic way to implement getters and setters is to use properties. This allows you to define getter, setter, and deleter methods in a single line of code:

class C(object):
    @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

c = C()
c.x = 'foo'  # setter called
foo = c.x    # getter called
del c.x      # deleter called
