Question

Write a program that calculates the balance of a savings account at the end of a three month period. It should ask the user for the starting balance and the annual interest rate. A loop should then iterate once for every month in the period, performing the following:

1. Ask the user for the total amount deposited into the account during that month. Do not accept negative numbers. This amount should be added to the balance.
2. Ask the user for the total amount withdrawn from the account during that month. Do not accept negative numbers or numbers greater than the balance after the deposits for the month have been added in.
3. Calculate the interest for that month. The monthly interest rate is the annual interest rate divided by 12. Multiply the monthly interest rate by the average of that month's starting and ending balance to get the interest for that month. This amount should be added to the balance.

After the last iteration, the program should display a final report that includes the following information:

• Starting balance at the beginning of the last three-month period
• Total deposit made during the last three-month period
• Total withdrawal made during the last three-month period
• Total interest posted to the account during the three months
• Final balance

Answer 1

Solution:

Note: Please refer the screenshot for indentation.

Code implementation:

balance=int(input("Enter Starting balance: "))
print(balance) #prints balance entered by the user.
annual_ir=int(input("Enter Annual interest rate: "))
print(annual_ir) # prints annual_ir entered by the user.
i=0 #iteration variable.
while(i<3):
print()
print("Month:",end=" ")
print(i+1)
i+=1
month_starting_balance=balance # month_starting_balance
print("Starting balance:",end=" ")
print(month_starting_balance)
amount_deposit=int(input("Enter deposit amount: "))
print(amount_deposit) # prints amount_deposit
while(amount_deposit<0): # checks for negative value.
amount_deposit=int(input("Enter deposit amount: "))
print(amount_deposit)
balance+=amount_deposit # adds amount deposited.
print("Amount deposited:",end=" ")
print(amount_deposit)
amount_withdraw=int(input("Enter withdraw amount: "))
print(amount_withdraw) #prints amount_withdrawn
# checks for negative and amount greater than balance.
while(amount_withdraw<0 or amount_withdraw>balance):
amount_withdraw=int(input("Enter withdraw amount: "))
print(amount_withdraw)
print("Amount withdrawn:",end=" ")
print(amount_withdraw)
balance-=amount_withdraw # subtracts the withdrawn amount from balance.
month_ending_balance=balance
monthly_interest=annual_ir/12 #monthly Interest.
interest_for_month=((month_starting_balance+month_ending_balance)/2)*monthly_interest
print("Ending balance:",end=" ")
print(month_ending_balance) # displays month end balance.
print("Interest posted:",end=" ")
print(interest_for_month) # displays interest for each month.
balance+=interest_for_month
print("Final balance:",end=" ")
print(balance) # displays balance for each month.
