== Why is this an issue? 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. === Noncompliant code example [source,python] ---- def foo(param): ls = [1, 2, 3] x, y = ls # Noncompliant ---- === Compliant solution [source,python] ---- def foo(param): ls = [1, 2, 3] x, y, z = ls ----
