Function Imports

Nice work! Now Python knows how to take the square root of a number.

However, we only really needed the `sqrt`

function, and it can be frustrating to have to keep typing `math.sqrt()`

.

It’s possible to import only certain variables or functions from a given module. Pulling in just a single function from a module is called a *function import*, and it’s done with the `from`

keyword:

from module import function

Now you can just type `sqrt()`

to get the square root of a number—no more `math.sqrt()`

!

### Instructions

**1.**

Let’s import *only* the `sqrt`

function from `math`

this time. (You don’t need the `()`

after `sqrt`

in the `from math import sqrt`

bit.)
