What are some examples of encapsulation in Python?

Encapsulation in Python is a fundamental concept of OOP that restricts access to certain components. For example, you can use private variables and methods in a class.

Can you show me a code example?

Sure! Here's a simple example:

class BankAccount:
    def __init__(self, balance):
        self.__balance = balance  # private variable

    def deposit(self, amount):
        self.__balance += amount

    def get_balance(self):
        return self.__balance

account = BankAccount(100)
account.deposit(50)
print(account.get_balance())  # Output: 150

What happens if I try to access __balance directly?

If you try to access __balance directly, you'll get an AttributeError because it's a private variable. You should use the provided methods to interact with it.

Are there any other ways to implement encapsulation?

Yes, you can also use properties in Python to control access to class attributes. This allows you to define getter and setter methods.
