<overview>
|
|
<p> An assignment statement evaluates a sequence expression and assigns each item of the sequence to
|
|
one of the variables on the left. If there is a mismatch between the number of variables on
|
|
the left and the values in the sequence on the right of the statement, then an exception is raised
|
|
at runtime.
|
|

|
|
<recommendation>
|
|
<p>Ensure that the number of variables on either side of the assignment match.</p>
|

|
<example>
|
|
<p>The following examples show a simple definition of the Fibonacci series. In the first example,
|
|
one of the values in the assignment has been duplicated, causing an exception at runtime.</p>
