Given items = [1, 2, 3, 4], what happens when items[::2] = [9] is executed?
It produces [9, 2, 4].
It accepts any replacement length.
It raises TypeError because stepped slices are read-only.
It raises ValueError because two positions need two values.✓Правильный ответ
Объяснение
The extended slice selects two positions, but the replacement supplies only one value, so Python raises ValueError. Unlike a simple slice, a stepped assignment cannot change the number of selected slots by using a differently sized replacement.
