Jul 25, 2024 · 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.
Learn what encapsulation is in Python and how to use public, protected, and private members in a class. See how to access and modify attributes and methods with different access modifiers.

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...

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 maintainableLearn what encapsulation is and how to implement it in Python using classes, access modifiers, and getter and setter methods. Encapsulation is a way to bundle data and methods within a single unit and hide internal representation from the outside.

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:
Encapsulation in Python is a powerful tool for creating robust and maintainable code. By encapsulating data and methods within classes, developers can control access to the internal state, promoting data protection, modularity, flexibility, and code reuse.
