I typed python -v in my terminal and something weird happened
<p>Thinking I was about to check the version of Python installed on my computer, I typed </p>

<pre><code>python -v 
</code></pre>

<p>in my terminal and I got a first line saying </p>

<blockquote>
  <p>"installing zipimport hook", but then also a whole bunch of text (probably 50 or so lines of text), among which "import errno # builtin", "import posix # builtin", "import _codecs # builtin", and toward the end "Python 2.7.8 |Anaconda 2.1.0 (x86_64)| (default, Aug 21 2014, 15:21:46)"</p>
</blockquote>

<p>What did I do? And what did that command install?</p>

<p><strong>EDIT</strong>: the <code>v</code> I typed in <code>python -v</code> was a lowercase <code>v</code>. When I now try an uppercase <code>V</code>, I do get the version of Python on my computer.</p>
