You need to add:
from math import sqrt

from cmath import sqrt

from numpy import sqrt
Each with their own, slightly different, meaning.
Hence the reason many of us prefer to import the module
and reference the function as a module attribute.
Note that _many_ (especially older) package documents describe
their code without the module name. I believe that such behavior
is because, when working to produce prose about a package, it
feels too much like useless redundancy when describing each function
or class as "package.name".
