Encapsulation:
--------------
Encapsulation is the process of binding of data (variables/attributes/properties) and methods together inside a class.
Restricting direct access to sensitive data.
=> to implement the encapsulation we need:
	private members ==> which are prefixed with __
	getters and setters

class BankAccount:
    def __init__(self,account_number,balance):
        self.account_number = account_number
        self.__balance = balance
    
    def get_balance(self):
        return self.__balance
        
    def deposit(self,amount):
        if amount > 0:
            self.__balance += amount
            print(f"Deposited Rs.{amount} New Balance =  Rs.{self.__balance}")
        else:
            print("Invalid depsit amount.")
        
    def withdraw(self,amount):
        if 0 < amount <= self.__balance:
            self.__balance -= amount
            print(f"Withdraw Rs.{amount} Remaining Balance =  Rs.{self.__balance}")
        else:
            print("Insufficient funds or Invalid withdrawl amount")

account = BankAccount("1234560789",45000)
print("My Account Balance = ",account.get_balance())

account.deposit(55000)    
account.withdraw(5000)
    
account.__balance = 500000    
print(account.get_balance())
