Understanding Getters and Setters in Python
An introduction to getters and setters in Python
In object-oriented programming, encapsulation is one of the fundamental principles, used to bundle the data (attributes) and methods (functions) that operate on the data into a single unit or class. It also restricts direct access to some of an object’s components, which can prevent the accidental modification of data. To achieve this in Python, we often use getters and setters. Let’s explore what these are and how they are implemented in Python.
What are Getters and Setters?
Getters and Setters are methods used to define or alter the values of instance variables. A getter method allows you to access or “get” the value of a private variable, while a setter method allows you to “set” or update the value of a private variable. This approach provides a controlled way of accessing and updating private variables in an object.
Why Use Getters and Setters?
1. Encapsulation: They keep the data safe from outside interference and misuse.
2. Validation: Setters provide a way to validate data before setting a property.
3. Flexibility: You can change the internal implementation without affecting the classes that use them.
4. Additional Logic: You can add additional…
