How do I make an input show up in a print statement in Python
<pre><code>def main():
    print "This program calculates the future value of a 10-year investment"

    principal = input("enter the initial principle: ")
    years = input("enter number of years you want to invest: ")
    apr = input("Enter the APR: ")

    for i in range(years):
        principal = principal * (1 + apr)

        print "The amount in" years "years is: " , years, principal

main()
</code></pre>

<p>i am getting an error here.  how do i get the final print statement to show the input value.</p>
