Pretty good level!

I’ve noticed this comment seems superfluous, and perhaps misleading:

```
# Complete the function. It must return the cube of the base
```

I believe you can just remove that comment, as there is already another comment right above the `power`

function that gives the correct guidance:

```
# This function returns the number to the exponent power.
```

Also, if the goal of these levels is to get players to implement these algorithms from scratch, perhaps you could blacklist things like JavaScript’s `Math.pow()`

and Python’s exponentiation operator (`**`

).
