Here is a short Python program.

```python
shift = 7
nums = [6, 7, 3]
score = 2
if shift == 4:
    score = nums[-1]
else:
    nums[0] = 8
    shift += score * 2
items = [7, 8, 2]
values = items
values += [17]
values = values + [21]
shift += len(items) + items[-1]
parts = [6, 0, 3, 2]
step = 0
for e in parts:
    if e > 5:
        step += e
    else:
        step -= 3
shift += step
delta = score
rate = 0
while delta < 14:
    delta += 2
    rate += 1
shift += rate + delta
shift += nums[-1]
```

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

To find the final value of `shift`, let's trace the program step-by-step:

1.  **Initial values:**
    `shift = 7`
    `nums = [6, 7, 3]`
    `score = 2`

2.  **First conditional:**
    `if shift == 4:` (7 == 4 is False)
    `else:`
    `nums[0] = 8` $\rightarrow$ `nums` is now `[8, 7, 3]`
    `shift += score * 2` $\rightarrow$ `shift = 7 + (2 * 2) = 11`

3.  **List operations:**
    `items = [7, 8, 2]`
    `values = items` (Both point to the same list)
    `values += [17]` $\rightarrow$ `items` and `values` are now `[7, 8, 2, 17]`
    `values = values + [21]` $\rightarrow$ `values` is now `[7, 8, 2, 17, 21]`, but `items` remains `[7, 8, 2, 17]`
    `shift += len(items) + items[-1]` $\rightarrow$ `shift = 11 + 4 + 17 = 32`

4.  **For loop:**
    `parts = [6, 0, 3, 2]`
    `step = 0`
    - `e = 6`: `6 > 5` is True $\rightarrow$ `step = 0 + 6 = 6`
    - `e = 0`: `0 > 5` is False $\rightarrow$ `step = 6 - 3 = 3`
    - `e = 3`: `3 > 5` is False $\rightarrow$ `step = 3 - 3 = 0`
    - `e = 2`: `2 > 5` is False $\rightarrow$ `step = 0 - 3 = -3`
    `shift += step` $\rightarrow$ `shift = 32 + (-3) = 29`

5.  **While loop:**
    `delta = score` $\rightarrow$ `delta = 2`
    `rate = 0`
    - Loop 1: `2 < 14` (True) $\rightarrow$ `delta = 4`, `rate = 1`
    - Loop 2: `4 < 14` (True) $\rightarrow$ `delta = 6`, `rate = 2`
    - Loop 3: `6 < 14` (True) $\rightarrow$ `delta = 8`, `rate = 3`
    - Loop 4: `8 < 14` (True) $\rightarrow$ `delta = 10`, `rate = 4`
    - Loop 5: `10 < 14` (True) $\rightarrow$ `delta = 12`, `rate = 5`
    - Loop 6: `12 < 14` (True) $\rightarrow$ `delta = 14`, `rate = 6`
    - Loop 7: `14 < 14` (False) $\rightarrow$ Exit loop.
    `shift += rate + delta` $\rightarrow$ `shift = 29 + 6 + 14 = 49`

6.  **Final operation:**
    `shift += nums[-1]` $\rightarrow$ `nums` is `[8, 7, 3]`, so `nums[-1]` is 3.
    `shift = 49 + 3 = 52`
