The second assignment:
vals = [0, 1, 2] vals[0], vals[2] = vals[2], vals[0]
- doesn’t change the list
- shortens the list
- extends the list
- reverses the list
Explanation: Let’s analyze this example:
- the list vals is created with the integer elements 0,1,2,
- using positive indices, the value in position 0 is swapped with the element in position 2,
- the elements are now in this order: 2,1,0. Therefore, the list has been reversed.
