 <p>But wait! There's more! Let's take another look at that strange line of code from <code>humansize.py</code>:
 
-<pre><code>if size < multiple:
+<pre><code>if size &lt; multiple:
     return "{0:.1f} {1}".format(size, suffix)</code></pre>
 
 <p><code>{1}</code> is replaced with the second argument passed to the <code>format()</code> method, which is <var>suffix</var>. But what is <code>{0:.1f}</code>? It's two things: <code>{0}</code>, which you recognize, and <code>:.1f</code>, which you don't. The second half (including and after the colon) defines the <i>format specifier</i>, which further refines how the replaced variable should be formatted.
