what am I doing wrong

from module import math


You import things(functions, objects etc) from libraries in python. They call them modules in python.

in your case you want to go into the math module(library) and import a function called sqrt like this

from math import sqrt


ah yea I see, thanks for your help


from math import *

This works


yep it will work too.
That statement imports all libraries form the math module into the workspace.


Import just the sqrt function from math on line 3!

from math import sqrt
