I have rewritten my "hypotenuse" program as follows:>>> #This program
calculates the width and diagonal of a golden rectangle
>>> print "Calculate the width and diagonal of a golden rectangle."
Calculate the width and diagonal of a golden rectangle.
>>> height = input ("Input height:")
Input height

But beware of the integer divison in

And for completeness that could also be written:
hypotenuse = pow(hyp_squared,1/2)
Again, without the need to import math.

assert 4**0.5 == 2
More generally: nth root of x: x ** (1.0/n)
Or even more generally, take the 3rd root of the square of x:
x ** (2.0/3.0)
And when we are already extending the scope of the mailing list to math
basics:
1.0/(x**2) == x**-2
(negating the power gives the inverse.)

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
