Write the output on execution of the following Python code : ```python P = [3, 5, 7, 4] P.insert(2, 3) P.extend([10, 6]) print(P) print(P.index(7)) print(P[::2]) ```

The correct answer is Subjective. **Output:** ``` [3, 5, 3, 7, 4, 10, 6] 3 [3, 3, 4, 6] ``` **Explanation:** 1. `P = [3, 5, 7, 4]` 2. `P.insert(2, 3)` inserts the value `3` at index `2`. The list becomes: `[3, 5, 3, 7, 4]`. 3. `P.extend([10, 6])` appends multiple elements to the list. It becomes: `[3, 5, 3, 7, 4, 10, 6]`. 4. `print(P)` prints the complete list. 5. `P.index(7)` finds the first occurrence of the element `7`. It is located at index `3`. 6. `P[::2]` uses string slicing with a step of 2, resulting in alternate elements: `3` (index 0), `3` (index 2), `4` (index 4), `6` (index 6). Output is `[3, 3, 4, 6]`.
