I need help with this assignment. Here is the code below to modify. This is the starting code. Thank you. You will need IDLE and a recent edition of Python (I use Python 3.8.1).

def calculate_future_value(monthly_investment, yearly_interest, years): # convert yearly values to monthly values monthly_interest_rate = yearly_interest / 12 / 100 months = years * 12

# calculate future value future_value = 0.0 for i in range(0, months): future_value += monthly_investment monthly_interest = future_value * monthly_interest_rate future_value += monthly_interest

return future_value

def main(): choice = "y" while choice.lower() == "y": # get input from the user monthly_investment = float(input("Enter monthly investment:\t")) yearly_interest_rate = float(input("Enter yearly interest rate:\t")) years = int(input("Enter number of years:\t\t"))

# get and display future value future_value = calculate_future_value( monthly_investment, yearly_interest_rate, years)

print("Future value:\t\t\t" + str(round(future_value, 2))) print()

# see if the user wants to continue choice = input("Continue? (y): ") print()

print("Bye!") if __name__ == "__main__": main()

Enhance the Future Value program Senie/ Erenl al 136 Exercise 4-1 In this evemcise you Wenhance the Future Value program in figure 3-15 so it validates he three user entries with messages that are something like these: Chapter 4 How to define and use functions and modules 7.

This will be the file for a module that stcres the get oato and get int) functions. So, delete the calculate future value() function, but keep the main) function and the if statement after the main) function. 10. Ie the main) function, delete everything inside the while Joop except the last statement that asks whether the user wants to continue. Within this loop, code two call statements that test the get_Boan(0 and get int) functions. 11. Run the program to test the two functions.

Coet inue (y/al7a I a NE open the future_valoe py file that's in this folder: ythes/exercises/cho4 close the file. Use the validation module in the Future Value program 12. Go back to the future value py file. Then, commeng out the get number and 2. Test the prongram, hut remember that it doesn't do any validation, so enter valid numbers get integer() functions. 13. Add an import statement that imports the validation module. Add two validation functions to the program 3 la prepuration for adding two functions named get float() and get into to the program, create a hierarchy chart or outline that includes those function The functions will he used to get valid numbers and integers from the user descrihed in the next steps. 14. Modify the code in the main() function so it uses the functions in the validation module. 4. Add a function named get float() to the program. This function should accent one argument, which is a prompt like "Enter monthly investment: ". Then, this function should use the input function to get an entry from the user using the prompt that's passed to it, and the entry should be converted to a float value. Next, this function should check this entry to make sure it's greater than 0. If it is, the entry is valid and the number should be returned to the calling statement. If it isa't, an appropriate eror message should be displayed, and the user should enter another value. To make this work, the function should use a while statement that gets an entry until it is valid. 5. Modify the main() function so it uses this function to get the monthly imestment entry. That tests the function. 6. Enhance the get foat) function so it gets three arguments: a prompl, a low validity value, and a high validity value, This function should work as before, eAcept the entry must be greater than the low value and less than or equal to the high value. If the entry is invalid, this function should display error messages like those above using the low and high arguments. OtherWise, should return the value to the calling statement
