Not sure how to go about this. Im trying to return the square root and for some reason i can't access the math library.

So as per the usual with these posts i think i have it right, but i can't import math to do this so i tried to access the math.sqrt directly. Alas I cannot so their must be another way that I'm not aware of to do this simple math problem. Thank you in advance for any replies.

squaring.py 
def square(number):
    number = math.sqrt(number)
    return number

Hey, read Steven's answer carefully there and you'll get it. I was a little tired doing this one and was on the same track as you at first. One last hint remember the difference between a number squared and a square root.

The instructions say, "In the body of the function return the square of the value passed in.". You won't need to get the square root of anything for this challenge.

They also give you the hint: "A square is the value multiplied by itself." so you won't need the math library either.
