Hmm. I am thinking what is that? let’s deep a dive with me. Before I start I want to ask some questions myself.

What is @property in Python?
When should I use the @Property function?
How to use the @property function? In this article, you will understand what exactly the Python @Property does.

What is the Property in Python? In Python property is a built-in function. Property function is helping to modify class attributes and give backward compatibility. But you should have a basic concept of Python classes and method. Because of the @property is typically used inside one.

When should I use the @Property function? Assume, You create a class that store user bank account information like a bank account number and balance. Let's create the class

class Account:
 """ A basic class that store bank account information """

 def __init__(self, bank_account: str, balance: float):
 self.bank_account = bank_account
 self.balance = balance
 self.account_information = dict(bank_account=self.bank_account, balance=self.balance)

 def __str__(self):
 return f"Bank Account: {self.bank_account} - balance: {self.balance}"


account = Account("0004-0067894712", 1000.50)
print(f"account number: {account.bank_account}")
print(f"Current balance: {account.balance}")
print(f"Account information: {account.account_information}")

# Output should look like this 
account number: 0004-0067894712
Current balance: 1000.5
Account information: {'bank_account': '0004-0067894712', 'balance': 1000.5}

Now, from this account we transfer the fund what will we get after calling the account_information attribute? Let’s transfer the balance and call the account_information attribute of the instance.
