<p>A collection of notes to go over in class, to keep things organized.</p>

<p>Let’s take a look at the class outline:</p>

<h2>git / gitHub<a class="headerlink" href="#git-github" title="Permalink to this headline">¶</a></h2>
<p>In general, most of you seem to have got the basics down:</p>
<blockquote>
<div><ul class="simple">
<li>creating a new file</li>
<li>adding it to git</li>
<li>pushing it to your fork of the class repo</li>
<li>making a “pull request” on gitHub.</li>
</ul>
</div></blockquote>
<p>Any conceptual questions?</p>
<p>Let’s go in and clean up Brian’s fork…</p>

<div class="section" id="exceptions">
<h2>Exceptions<a class="headerlink" href="#exceptions" title="Permalink to this headline">¶</a></h2>
<p>Most of you seemed to do fine making the few key exceptions – any questions?</p>
<p><strong>Note:</strong></p>
<p>We were not expecting you to catch the exceptions – we’re really starting at the bottom here, just making sure you get used to seeing Exceptions, and what they mean.</p>
<p>We’ll get into Exception handling later.</p>
<div class="section" id="eval-exec">
<h3>eval / exec<a class="headerlink" href="#eval-exec" title="Permalink to this headline">¶</a></h3>
<p>One of you used <code class="docutils literal"><span class="pre">eval</span></code> to demonstrate a syntax error:</p>
<p>Which is a nifty way to get a Syntax Error without crashing the interpreter.</p>
<p>But we were actually expecting you to crash the interpreter! That’s kinda what syntax errors are about.</p>
<p>General Advice: <strong>don’t use eval or exec</strong></p>
<p>Why not?</p>
<blockquote>
<div><ul class="simple">
<li>dangerous!</li>
<li>unnecessary – metaprograming! – we’ll get to that second quarter.</li>
</ul>
