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.)
