Each value in an array $($in the above case, the numbers $0\mathrm{.}125,4\mathrm{.}75,$ and $-1\mathrm{.}3)$ is called an element of that array.

Arrays themselves are also values, just like numbers and strings. That means you can assign them to names or use them as arguments to functions. For example, len$()$ returns the number of elements in some$\_$array.

Question $4\mathrm{.}1\mathrm{.}1.$ Make an array containing the numbers $0,1,-1,$

$,$ and

$,$ in that order. Name it interesting$\_$numbers.

Hint: math.pi is the value of

and math.e is the value of

$.$
