<overview>

<p>A non-existent attribute of <code>self</code> is accessed in a method.

An attribute is treated as non-existent if it is not a class attribute

and it is not set in any method of the class.

This may result in an <code>AttributeError</code> at run time.

</p>

</overview>

<recommendation>

<p>Ensure that all attributes are initialized in the <code>__init__</code> method.</p>
