What is data encapsulation in Python?

Data encapsulation is a fundamental concept in object-oriented programming that restricts direct access to some of an object's components. In Python, this is typically achieved using private and protected attributes.

Can you give me an example of how to implement data 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 withdraw(self, amount):
        if amount <= self.__balance:
            self.__balance -= amount
        else:
            print('Insufficient funds')

    def get_balance(self):
        return self.__balance

What are the benefits of using data encapsulation?

The benefits include improved data security, easier maintenance, and better control over how data is accessed and modified.

Are there any drawbacks to data encapsulation?

Yes, it can lead to increased complexity and may require more code to manage access methods.
