How do I use encapsulation in Python?

Encapsulation in Python is a way to restrict access to certain components of an object. You can achieve this by using private and protected attributes.

Can you give me an example of encapsulation?

Sure! Here's a simple example:

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

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

    def get_balance(self):
        return self.__balance

What happens if I try to access __balance directly?

If you try to access __balance directly from outside the class, you'll get an AttributeError. This is because it's a private attribute.

How can I access the balance then?

You can access the balance using the get_balance() method, which is a public method that returns the value of the private attribute.
