Jul 25, 2024 · Encapsulation in Python. Encapsulation is one of the fundamental concepts in object-oriented programming (OOP). It describes the idea of wrapping data and the methods that work on data within one unit. This puts restrictions on accessing variables and methods directly and can prevent the accidental modification of data.
In Python, encapsulation is achieved through the use of access modifiers. These access modifiers control the visibility of class attributes and methods from outside the class. The three common access modifiers are: Public: Members are accessible from outside the class. Protected: Members are accessible within the class and its subclasses.

Encapsulation in Python describes the concept of bundling data and methods within a single unit. So, for example, when you create a class, it means you are implementing encapsulation. A class is an example of encapsulation as it binds all the data members (instance variables) and methods into a single unit. Example: In this example, we create an Em...
Encapsulation can be achieved by declaring the data members and methods of a class either as private or protected. But In Python, we don’t have direct access modifiers like public, private, and protected. We can achieve this by using single underscore and double underscores. Access modifiers limit access to the variables and methods of a class. Pyt...
Public data members are accessible within and outside of a class. All member variables of the class are by default public. Example: Output
We can protect variables in the class by marking them private. To define a private variable add two underscores as a prefix at the start of a variable name. Private members are accessible only within the class, and we can’t access them directly from the class objects. Example: Output In the above example, the salary is a private variable. As you kn...
Protected members are accessible within the class and also available to its sub-classes. To define a protected member, prefix the member name with a single underscore _. Protected data members are used when you implement inheritanceand want to allow data members access to only child classes. Example: Proctecd member in inheritance. Output
To implement proper encapsulation in Python, we need to use setters and getters. The primary purpose of using getters and setters in object-oriented programs is to ensure data encapsulation. Use the getter method to access data members and the setter methods to modify the data members. In Python, private variables are not hidden fields like in othe...
Security: The main advantage of using encapsulation is the security of the data. Encapsulation protects an object from unauthorized access. It allows private and protected access levels to prevent...Data Hiding: The user would not be knowing what is going on behind the scene. They would only be knowing that to modify a data member, call the setter method. To read a data member, call the getter...Simplicity: It simplifies the maintenance of the application by keeping classes separated and preventing them from tightly coupling with each other.Aesthetics: Bundling data and methods within a class makes code more readable and maintainableIn a nutshell, encapsulation in Python allows us to restrict the access to certain methods and variables within the class, ensuring that the data is hidden and safe from any unintentional modifications.

Apr 29, 2024 · Encapsulation is a fundamental object-oriented principle in Python. It protects your classes from accidental changes or deletions and promotes code reusability and maintainability. Consider this simple class definition: class Smartphone: def __init__(self, brand, os): self.brand = brand. self.os = os.
Dec 7, 2023 · Encapsulation is the practice of keeping a class’ implementation details a secret and revealing only the information required for external interactions. Using the double underscore (__) prefix to declare a class variable private and using a getter method to access it are two examples of encapsulation in Python.
