Total Python Noob

[Tom Lake]

I have Python 2.6 installed on Vista Ultimate. When I try to calculate
sqrt (or any transcendental functions) I get the following error

>>sqrt(2)

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'sqrt' is not defined

What am I doing wrong?

do 'from math import sqrt' first

or try '2**0.5'

They're not buitltin, they're in the 'math' module
(http://docs.python.org/library/math.html#module-math), which you need
to import.
e.g.
import math
print math.sqrt(4)
