Hi! I need help with program exericse #6 entitled "Futval.py" which is a
program that computes the value of an investment carried 10 years into the
future.
This is the coding I have.. yet it does not seem to spit out the correct
numbers (Am I using an incorrect equation?)
*def main():
print "This program calculates the future value"
print "of a 10-year investment."
principal = input("Enter the amount invested each year: ")
apr = input("Enter the annual interest rate: ")
years = input("Enter the number of years: ")
for i in range (1, years + 1):
principal = principal * (1 + apr)**i
print "The value in", i, " years is:", principal
main()*
The output is suppose to appear like this:
This program calculates the future value of a 10-year investment.
Enter the amount invested each year: 100.00
Enter the annual interst rate: 0.05
Enter the number of years: 10
The value in 1 years is 105.0
The value in 2 years is 215.25
The value in 3 years is 331.0125
The value in 4 years is 452.563125
And so on..
^Please help me!!!
