Sonia has a list called colleges with 10 entries and wants to print the final item on the list. Which code should be used?

To print the final item on the list, you can use the indexing feature of Python by accessing the last element using the index `-1`.

Here's the code you should use:

```python
colleges = ["college1", "college2", "college3", "college4", "college5", "college6", "college7", "college8", "college9", "college10"]
print(colleges[-1])
```

This will output the final item in the list, which in this case is `"college10"`.
