Encapsulation with Getters/Setters
Use properties to encapsulate attribute access with getter and setter logic.

Python Encapsulation with Getters/Setters Program
This program helps you to learn the fundamental structure and syntax of Python programming.
# Program to demonstrate encapsulation using properties
class Account:
def __init__(self, balance=0):
self._balance = balance
@property
def balance(self):
return self._balance
@balance.setter
def balance(self, amount):
if amount < 0:
raise ValueError("Balance cannot be negative")
self._balance = amount
acc = Account(100)
print(acc.balance)
acc.balance = 150
print(acc.balance)Output
100 150
Understanding Encapsulation with Getters/Setters
The @property decorator allows attribute-style access while still enforcing validation in the setter.
Note: To write and run Python programs, you need to set up the local environment on your computer. Refer to the complete article Setting up Python Development Environment. If you do not want to set up the local environment on your computer, you can also use online IDE to write and run your Python programs.
