<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.
