[Tutor] hypotenuse

[Robert Childers]

I am in an early lesson in "A Byte of Python."  Instead of writing a program
to find the area of a rectangle I thought it would be useful to write a
program to determine the length of the diagonal of a "golden rectangle",
which would of course equal the sq root of the sum of the squares of
the width and height.  Here is my program:
>>> height = input ("Height:")
Height:1
>>> width = input ("Width:")
Width:1.618
>>> int = ((height**2) + (width**2))
>>> print int
3.617924
>>> hypotenuse * hypotenuse = int
SyntaxError: can't assign to operator

I looked ahead in the lesson and could find no mention of square roots.  How
do I find the square root of an integer?
