Encapsulation is the concept of hiding the internal implementation details of an object from the outside world. This is achieved by using access modifiers such as public, private, and protected.
account = BankAccount("1234567890", 1000) print(account.get_balance()) # Output: 1000 account.deposit(500) print(account.get_balance()) # Output: 1500

In conclusion, Python 3 provides an excellent platform for implementing OOP principles. By understanding the concepts of classes and objects, inheritance, polymorphism, encapsulation, and abstract classes and interfaces, developers can create robust, scalable, and maintainable software systems. By following best practices and using design patterns, developers can write high-quality code that is easy to understand, modify, and extend.
