<overview>

<p>

The <code>super</code> class should be called with the enclosing class as its first argument and <code>self</code> as its second argument.

</p>

<p>

Passing a different class may work correctly, provided the class passed is a super class of the enclosing class and the enclosing class

does not define an <code>__init__</code> method.

However, this may result in incorrect object initialization if the enclosing class is later subclassed using multiple inheritance.

</p>

</overview>

<recommendation>

<p>

Ensure that the first argument to <code>super()</code> is the enclosing class.

</p>

</recommendation>

<example>

<p>

In this example the call to <code>super(Vehicle, self)</code> in <code>Car.__init__</code> is incorrect as it

passes <code>Vehicle</code> rather than <code>Car</code> as the first argument to <code>super</code>.

As a result, <code>super(SportsCar, self).__init__()</code> in the <code>SportsCar.__init__</code> method will not call

all <code>__init__()</code> methods because the call to <code>super(Vehicle, self).__init__()</code>

skips <code>StatusSymbol.__init__()</code>.
