<overview>
<p>This place-holder variable may not be defined.
If this code is executed and the variable is undefined then a <code>NameError</code> will occur.
</p>

</overview>
<recommendation>

<p>Check that the name of the place-holder variable is not a typographic error.
If the name is correct, either define a value for the variable, or import the module that defines the function or method that sets the value.
</p>

<p>If another module initializes this variable before it is used, then the <code>NameError</code> may not occur.
However, you can make the code more robust and clearer by setting the variable to a default value in its own module.
