How to sum numbers from input?
<p>I am working on the following problem.</p>

<p>Write a program that continually prompts for positive integers and stops when the sum of numbers entered exceeds 1000. 
But my code stop early if a negative integer is entered.</p>

<p>The numbers will not sum.</p>

<p>My code:    </p>

<pre><code>x = int(input("Enter an integer:"))
total = 0
sum = 0
while (0 &lt;= x):
    if sum &lt;= 1000:
        x += 1
        sum += (int(input("Enter an integer:")))
    elif sum &gt;= 1000:
        break
</code></pre>
