Exam PCEP-30-02 topic 1 question 3 discussion

The given code performs the following operations: 1. `x = [0, 1, 2]`: Initializes the list `x` with the elements `[0, 1, 2]`. 2. `x.insert(0, 1)`: Inserts the value `1` at index `0`, so the list becomes `[1, 0, 1, 2]`. 3. `del x[1]`: Deletes the element at index `1`, so the list becomes `[1, 1, 2]`. 4. `print(sum(x))`: Calculates the sum of the elements in the list `x` and prints it. Now, the list `x` is `[1, 1, 2]`, and the sum of these elements is `1 + 1 + 2 = 4`. **Expected output:** `4`

x.insert(0,1) >> insert value 1 to x[0] >> The new x = [1,0,1,2] del x[1] >> delete x[1] >> delete value 0 in x sum(x) = 1+1+2 = 4

b is the correct answer
