import math
x = math.sin(y)

Notice that the math. is needed because the form of the import statement
doesn't put the functions into the namespace.

from math import sin
x = sin(y)

This allows you to get by without the qualification, but there are other
reasons
why you might not want to do it that way.

As far as string goes, it's usually better to use the string methods rather
than
the string module.
