Here's what your code did:

import math  # make the math module accessible
a = math.sqrt(1000)  # set `a` to the square root of 1000 (≈31.62...)
a.sqrt  # get a reference to the sqrt method/attribute of a float, which
does not exist; moreover you are not calling the method/discarding the
value so it would be useless anyways
