Here is a short Python program.

```python
base = 2
nums = [3, 3, 1, 3]
height = 4
nums.extend([base, 9])
base += len(nums)
base += height
```

After this program runs, what is the value of `base`? Work through it carefully, then give the final answer on its own last line as `ANSWER: <python literal>`.

Let's trace the execution of the Python code step by step:

1. `base = 2`: The variable `base` is initialized to 2.
2. `nums = [3, 3, 1, 3]`: The list `nums` is initialized to `[3, 3, 1, 3]`.
3. `height = 4`: The variable `height` is initialized to 4.
4. `nums.extend([base, 9])`: The list `nums` is extended by the list `[base, 9]`. Since `base` is currently 2, `nums` becomes `[3, 3, 1, 3, 2, 9]`.
5. `base += len(nums)`: The value of `base` is updated by adding the length of `nums`. The length of `nums` is 6, so `base` becomes `2 + 6 = 8`.
6. `base += height`: The value of `base` is updated by adding the value of `height`. Since `height` is 4, `base` becomes `8 + 4 = 12`.

Therefore, the final value of `base` is 12.

ANSWER: 12
