<overview>

<p>If the object raised is not a legal Exception class or an instance of one, then

a <code>TypeError</code> will be raised instead.</p>

<p>Legal exception classes are:</p>

<ul>

<li>Any old-style classes (Python 2 only)</li>

<li>Any subclass of the builtin class <code>BaseException</code></li>

</ul>

<p>

However, it recommended that you only use subclasses of the builtin class

<code>Exception</code> (which is itself a subclass of <code>BaseException</code>).

</p>

</overview>

<recommendation>

<p>Change the expression in the <code>raise</code> statement to be a legal exception.</p>

</recommendation>
