# How to do it...

1. The following code (time.py) uses the Pythagorean Theorem to calculate the hypotenuse for a number of triangles with increasing side lengths:
`        import math        TIMES = 10000000        a = 1        b = 1         for i in range(TIMES):            c = math.sqrt(math.pow(a, 2) + math.pow(b, 2))            a += 1            b += 2`
1. The following code (time2.py) does the same thing as pythag_theorem.py but puts the calculations within a function, rather than performing the calculation in line:
`        import math        TIMES = 10000000        a = 1        b = 1         def calcMath(i, a, b):            return math.sqrt(math.pow(a, 2) + math.pow(b, 2))         for i in range(TIMES):            c = calcMath(i, a, b)            a += 1            b += 2 `
