 <h2 id="divingin">Diving in</h2>
 <p class="fancy">You know how other books go on and on about programming fundamentals and finally work up to building something useful?  Let's skip all that.  Here is a complete, working Python program.  It probably makes absolutely no sense to you.  Don't worry about that, because you're going to dissect it line by line.  But read through it first and see what, if anything, you can make of it.

 <h2 id="declaringfunctions">Declaring functions</h2>
 <p>Python has functions like most other languages, but it does not have separate header files like <abbr>C++</abbr> or <code>interface</code>/<code>implementation</code> sections like Pascal.  When you need a function, just declare it, like this:
 <pre><code>def approximate_size(size, a_kilobyte_is_1024_bytes=True):</code></pre>
