Question

I am trying to create a ATM style bank program that accept the customer id , in the welcoming panel ,but how do i make when the customer input their id# and click on the ok button then they have 3 or so tries to input the correct id# and if successful then send to the other panel where they choose which transaction to they want to make for example savings , checking account , make and deposit , and check balance and when finish exit the program

In your answer please include how to bind the input your id function to the customer id on the welcoming panel

Include how to switch between the panels

Please include only working codes

Here is my example code :

class Account(object):
    def __init__(self):
        self.balance = 0
      
    def deposit(self, amount):
        if (amount < 0):
            return 'Please deposit an amount greater than 0'
        self.balance += amount
        print ('Amount deposited {}'.format(amount))
        return 'SUCCESS'
      
    def withdraw(self, amount):
        if (amount < 0):
            return 'Please withdraw an amount greater than 0'
        if (amount > self.balance):
            return 'Please enter an amount less than your account balance'
        self.balance -= amount
        return 'SUCCESS'
  
    def balance(self):
        return self.balance

class SavingsAccount(Account):
    def __init__(self, interestRate):
        super(SavingsAccount, self).__init__()
        print ('Your savings account has been opeend')
        self.interest_rate = interestRate
        self.interest = 0
  
    def compute_interest(self):
        self.interest = self.balance * self.interest_rate
      
    def get_interest(self):
        return self.interest

class CheckingAccount(Account):
    def __init__(self):
        super(CheckingAccount, self).__init__()

def main():
    interestRate = 3 # test run with 3% interest rate
    SavingsObject = SavingsAccount(interestRate)
  
    initialBalance = SavingsObject.balance()
    print ('Initial account balance is {}'.format(initialBalance))
  
    amountToDeposit = 300
    SavingsObject.deposit(amountToDeposit)
    balanceAfterDeposit = SavingsObject.balance()
    print ('Your account balance is {}'.format(balanceAfterDeposit))
  
if __name__ == "__main__":
    main()

Below is the code with the required functionalities:

class Account(object):

def __init__(self):

self.balance = 0

def deposit(self, amount):

if(amount < 0):

return 'Please deposit an amount greater than 0'

self.balance += amount

print ('Amount deposited {}'.format(amount))

return 'SUCCESS'

def withdraw(self, amount):

if(amount < 0):

return 'Please withdraw an amount greater than 0'

if(amount > self.balance):

return 'Please enter an amount less than your account balance'

self.balance -= amount

return 'SUCCESS'

def balance1(self):

return self.balance

class SavingsAccount(Account):

def __init__(self, interestRate):

super(SavingsAccount, self).__init__()

print ('Your savings account has been opeend')

self.interest_rate = interestRate

self.interest = 0

def compute_interest(self):

self.interest = self.balance * self.interest_rate

def get_interest(self):

return self.interest

class CheckingAccount(Account):

def __init__(self):

super(CheckingAccount, self).__init__()

def main():

flag = 0

for i in range(0,3):

customer_id = input("Enter the Customer ID: ")

if(isValid(customer_id)):

flag = 1

break

else:

if(i==2):

break

print("That's not a valid ID! You have", 2-i, "more chances!")

if(flag==1):

welcomePanel(customer_id)

else:

print("You entered the Customer ID incorrectly 3 times!!!")

print("Exiting the program!")

def isValid(customer_id):

#Insert here the code of checking whether the customer id is valid or not.

#If it is valid, return True, else return False

return True

def welcomePanel(customer_id):

print("MAIN MENU")

print("1. Open a savings account.")

print("2. Check account.")

print("3. Deposit money.")

print("4. Withdraw money.")

print("5. Check balance.")

print("6. Exit.")   

choice = int(input("\nEnter your choice(1-6): "))

interestRate = 3 # test run with 3% interest rate

SavingsObject = SavingsAccount(interestRate)   

if(choice==1):

initialBalance = SavingsObject.balance1()

print ('Initial account balance is {}'.format(initialBalance))

elif(choice==2):

#Insert code to check account. Your CheckingAccount class is incomplete.

return

elif(choice==3):

amountToDeposit = int(input("Please enter the amount to deposit: "))

SavingsObject.deposit(amountToDeposit)

balanceAfterDeposit = SavingsObject.balance1()

print ('Your account balance is {}'.format(balanceAfterDeposit))

elif(choice==4):

amountToWithdraw = int(input("Please enter the amount to withdraw: "))

SavingsObject.withdraw(amountToWithdraw)

balanceAfterWithdraw = SavingsObject.balance1()

print ('Your account balance is {}'.format(balanceAfterDeposit))

elif(choice==5):

print ('Your account balance is {}'.format(SavingsObject.balance1()))

else:

print("Exiting the program!")

if __name__ == "__main__":

main()

Two new functions have been made: isValid() and welcomePanel().

In the main function, the user is asked to enter the customer ID. If he enters an invalid ID, he is asked to enter the valid ID, and he can only enter ID thrice, as mentioned in the requirements.

If he enters the invalid ID all the three times, the program exits saying "You entered the Customer ID incorrectly 3 times!!!". (This output line, however, can be changed as per your preference.) The output in this case is:

The decision of whether the ID is valid or not is based on the implementation of the function isValid(customer_id). The student can write his/her code for checking whether the ID is valid or not, as there can be an infinite number of ways to check that, and it depends on the design of the system.

Now, if the customer enters a valid CustomerID, the control shifts to another function, the welcomePanel(). Here, the user can choose which transaction do they want to make, like opening a savings account, depositing or withdrawing money, checking balance, etc. Depending on the choice they have entered, the corresponding function is performed, and the control shifts back to the main() panel(or function). This is how switching between the two panels is carried out. The sample output is given below:

I've just provided the main underlying structure behind the problem, but inserting the code for mentioned functionalities is dependent on the user.

(Note: I have changed the name of the function balance() to balance1() since it was clashing with the variable balance.)
