Trouble with simple Python Code
<p>I'm learning Python, and I'm having trouble with this simple piece of code:</p>

<pre><code>a = raw_input('Enter a number: ')

if a &gt; 0:
    print 'Positive'
elif a == 0:
    print 'Null'
elif a &lt; 0:
    print 'Negative'
</code></pre>

<p>It works great, apart from the fact that it always prints 'Positive', no matter if i enter a positive or negative number or zero. I'm guessing there's a simple solution, but i can't find it ;-)</p>

<p>Thanks in advance</p>
