How to loop through a percentage investment?
<p>I'm working on this simple task where a financial advisor suggests to invest in a stock fund that is guaranteed to increase by 3 percent over the next five years. </p>

<p>Here's my code:</p>

<pre><code>while True:
    investment = float(input('Enter your initial investment: '))
    if 1000 &lt;= investment &lt;= 100000:
        break
    else:
        print("Investment must be between $1,000 and $100,000")


#Annual interest rate 
apr = 3 / 100
amount = investment

for yr in range(5):
    amount = (amount) * (1. + apr)
    print('After {:&gt;2d} year{} you have:   $ {:&gt;10.2f}'.format(yr, 's,' if yr &gt; 1 else ', ', amount))
</code></pre>
