Unpacking lets developers assign values of an iterable simultaneously to different targets in a single assignment.
|
||
|
|
However, for this assignment to work, the iterable should have the same number of elements as there are targets in the target list.
|
||
|
|
If this is not respected, a `ValueError` will be produced at runtime.
