Here is a short Python program.

```python
credit = 5
cells = [7, 5]
scores = [8, 0]
if credit < 7:
    scores.append(8)
cells.extend([4, 2])
if credit < credit:
    credit = scores.pop()
else:
    credit = scores.pop()
credit = scores.pop()
credit += len(cells)
scores.append(7)
values = [9, 1, 0]
bins = values
bins += [15]
credit += len(values) + values[-1]
cells = scores[1:]
cells = cells + [3]

def measure(val, amt=5):
    return val * 2 + amt

scores = scores[1:]
scores.extend([0, 9])
```

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

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

1.  `credit = 5`
2.  `cells = [7, 5]`
3.  `scores = [8, 0]`
4.  `if credit < 7:` (5 < 7 is True)
    *   `scores.append(8)` $\rightarrow$ `scores` is now `[8, 0, 8]`
5.  `cells.extend([4, 2])` $\rightarrow$ `cells` is now `[7, 5, 4, 2]`
6.  `if credit < credit:` (5 < 5 is False)
    *   Go to `else` block.
    *   `credit = scores.pop()` $\rightarrow$ `scores` was `[8, 0, 8]`, so `credit` becomes `8` and `scores` becomes `[8, 0]`.
7.  `credit = scores.pop()` $\rightarrow$ `scores` was `[8, 0]`, so `credit` becomes `0` and `scores` becomes `[8]`.
8.  `credit += len(cells)` $\rightarrow$ `len(cells)` is 4. `credit = 0 + 4 = 4`.
9.  `scores.append(7)` $\rightarrow$ `scores` is now `[8, 7]`.
10. `values = [9, 1, 0]`
11. `bins = values` (Both point to the same list object).
12. `bins += [15]` $\rightarrow$ `values` and `bins` are now `[9, 1, 0, 15]`.
13. `credit += len(values) + values[-1]`
    *   `len(values)` is 4.
    *   `values[-1]` is 15.
    *   `credit = 4 + 4 + 15 = 23`.
14. `cells = scores[1:]` $\rightarrow$ `scores` is `[8, 7]`, so `cells` becomes `[7]`.
15. `cells = cells + [3]` $\rightarrow$ `cells` becomes `[7, 3]`.
16. `def measure(val, amt=5): ...` (Function definition, does not affect `credit`).
17. `scores = scores[1:]` $\rightarrow$ `scores` becomes `[7]`.
18. `scores.extend([0, 9])` $\rightarrow$ `scores` becomes `[7, 0, 9]`.

The final value of `credit` was calculated at step 13 and not modified thereafter.
