Question

Answer in Python: Show all code:

Modify the code used to solve the below question so that calcFinalBalance() returns the final balance to main(), and main() prints the final balance out:

Write a program that contains a main function and a called function called calcFinalBalance(). The main function asks the user for the amount of money to be deposited in a bank account, the interest rate, and the number of years it will be in that account. The interest rate should be given as a percentage such as 5 or 4.2 (and not .05 and .042.) The main function passes these values to calcFinalBalance(). The calcFinalBalance function calculates the final balance and prints out this value. Assume interest is paid annually.

------------------------------------------------

# called function
def calcFinalBalance(amount, rate, years):
# change the formula accordingly, program remains same
# simple interest = (principal * period * rate of interest)/100
# final amount = principal + simple interest
  
interest = (amount * years * rate) / 100
balance = amount + interest
  
# return the balance
return balance

# main function
def main():
# get the user input
amount = float(input("Enter amount of money to be deposited in bank : "))
rate = float(input("Enter annual rate of interest : "))
years = int(input("Enter the number of years amount will be in that account : "))
# function call
balance = calcFinalBalance(amount, rate, years)
# print the returned result
print("\nFinal balance : ", balance)

# frequently python does not use main function..
# directly python executes the independent statements as the start of python program
# as we have used main function, the below statements required to call main function
if __name__== "__main__":
main()

OUTPUT ::

Result executed in 8.797 sec(s) Enter amount of money to be deposited in bank : 1000 Enter annual rate of interest : 4.2 Enter the number of years amount will be in that account : 2 Final balance : 1084.0
