Encapsulation in Python | Complete Guide with Examples
In this video, we explore encapsulation in Python – one of the core pillars of object-oriented programming. Encapsulation is all about bundling your data and methods together while protecting the data from outside interference. Think of it like a money box or a bank account: you can only interact with it through controlled access points, keeping your data safe and predictable.
You'll learn how Python implements encapsulation using public, protected, and private members, getters and setters, and the clever name mangling trick that enforces rules for private attributes. By the end of this video, you'll understand how to write safer, cleaner, and more maintainable code using encapsulation.
