What does this message mean? from: can't read /var/mail/ex48 (Learn Python the Hard Way ex49)
<p>In ex49, we are told to call the the lexicon.py file created in ex48 with the following command.</p>

<p>When I try to import the lexicon file with the following command</p>

<pre><code>    &gt;&gt;&gt; from ex48 import lexicon
</code></pre>

<p>it returns the following:</p>

<pre><code>    from: can't read /var/mail/ex48
</code></pre>

<p>I've tried looking this up. What does this mean? Is a file in the wrong place?</p>
