# ## 3. BankAccount

# 1. Create a Python class called  `BankAccount`  which represents a bank account, having as attributes:  `accountNumber`,  `name` , `balance`.
# 2.  Create a  **constructor**  with parameters:  `accountNumber`, `name`, `balance`.
# 3.  Create a  `deposit()`  method which manages the deposit actions. (deposit() method will take parameter d and you will increase the balance with the amount d)
# 4.  Create a  `withdrawal()` method which manages withdrawals actions. (withdrawal() method will take parameter w, you will reduce the amount of balance with w, if w is larger than the balance: then print `Impossible operation! Insufficient balance!"`)
# 5.  Create a `bankFees()` method to apply the bank fees with a percentage of 5% of the balance account. (When this method is called, the balance amount should reduce 5%)
# 6.  Create a  `display()` method to display account details.
