String substitution in Python 3?
<p>I'm trying to do something like this:</p>

<pre><code>subs = 'world'
"Hello {[subs]}"
</code></pre>

<p>in Python 3.</p>

<p>I can't quite figure out the syntax (having come from Ruby/PHP). Am I missing something? The % operator in the docs I think is Python 2.x deprecated.</p>
