Assume that play_list refers to a non-empty list, and that all its elements are integers. Write a statement that associates a new value with the first element of the list. The new value should be equal to twice the value of the last element of the list.

The solution code is written in Python.

play_list = [2, 4, 6, 8, 10] play_list[0] = 2 * play_list[len (play_list) - 1] print (play_list)

Explanation:

Firstly, we create a non-empty list, play_list, and fill it up with five random integers (Line 1).

To associate the new value with the first element of the list, we use expression play_list[0]. The index 0 address to the first element of the list.

Next, we use expression, len (play_list) - 1 to get the last index of the list and use that calculated last index to take out the last element and multiply it with 2. The result of multiplication is assigned to the first element, play_list[0] (Line 2).

When we print the list, we shall get

[20, 4, 6, 8, 10]
