Python / Strings / Consonants
<p>I'm trying to get my head around, how to get a representation of consonants in a sentence. 
Code I'm using just now doesn't seem to do the job:</p>

<pre><code>vowels = ("aeiou")
count = 0
for x in text:
    if not x in vowels:
        count += 1
</code></pre>

<p>In example " hello world " as an input, I receive 8 consonants. 
Many thanks in advance.</p>
