Focus on classes, objects, methods and good programming style
Your task is to create a BankAccount class using Python and Write an overall header comment for every function - use the IPO notation.
| Class name | BankAccount |
| Attributes |
__balance float float __pin integer integer |
| Methods |
__init_()
|
The bank account will be protected by a 4-digit pin number (i.e. between 1000 and 9999). The pin should be generated randomly when the account object is created. The initial balance should be 0.
get_pin()should return the pin.
check_pin(pin) should check the argument against the saved pin and return True if it matches, False if it does not.
deposit(amount) should receive the amount as the argument, add the amount to the account and return the new balance.
withraw(amount) should check if the amount can be withdrawn (not more than is in the account), If so, remove the argument amount from the account and return the new balance if
the transaction was successful. Return False if it was not.
get_balance() should return the current balance.
Finally, write a main() to demo your bank account class. Present a menu offering a few actions and perform the action the user requests, checking the pin where appropriate.
1. New Account – if selected, create a new account and tell the user the pin.
2. Deposit – if selected, prompt the user to input the pin, check the pin and then, if correct, prompt for the amount to deposit. Process the deposit and report the new balance.
3. Withdraw – if selected, prompt the user to input the pin, check the pin and then, if correct, prompt for the amount to withdraw. Process the withdrawal and report the new balance or a
message if the transaction was not successful.
4. Check balance – if selected, prompt the user to input the pin, check the pin and then, if correct, call the get_balance method and report the balance.
All printed output should be done in main(), not the methods.
Sample run
Choose: (N) New account, (D) Deposit, (W) Withdraw, (C) Check balance (S)Stop

Withdrawing
Amount to withdraw: 176
Cannot withdraw that amount.
Choose: (N) New account, (D) Deposit, (W) Withdraw, (C) Check Balance (S) Stop
