Question

Using python, produce code that mimics some ATM transactions:

a. A welcome message must be displayed initially reflecting the appropriate time of day (for example: Good Night, Welcome to Sussex Bank).

b. Assume the user’s account balance is $5375.27.

c. Allow the user to enter a pin number that does not have to be validated: def atm_login(): pin_number = input("Please enter your (4 digit) pin number: ") # display welcome message welcome_message()

d. The message should be followed by a display of menu options: balance enquiry, deposit, withdrawal, and exit (for example: “Enter 1 – To perform a balance enquiry.”) as the user is prompted to make their selection.

NB - Note in some cases you must make certain considerations (for example in the case of a withdrawal – Insufficient funds, the balance is only $$$ and in the case of deposits – Amount must be greater than $0 so to take care of negative deposits)

e. Importantly, this program must be continuous until broken by the option to exit and reflect all current balances with respect to transactions undertaken by user. For example: account balance once initialized as 5375.27, will display 5375.27 for balance enquiry given selection of 1. If followed by withdrawal of 500.00 given selection of 2, new account balance should display 4875.27 and so on… until broken by selection to exit

#import datetime that helps to print greetiing like Good morning,Good Evening and Good Night
import datetime
currentTime = datetime.datetime.now()
currentTime.hour
#Function to print Welcome Message
def welcome_message():
    if currentTime.hour < 12:
     print('Good morning, Welcome to Sussex Bank')
    elif 12 <= currentTime.hour < 18:
