http://projecteuler.net/problem=9 A Pythagorean triplet is a set of three natural numbers, a < b < c, for which, a2 + b2 = c2 For example, 32 + 42 = 9 + 16 = 25 = 52. There exists exactly one Pythagorean triplet for which a + b + c = 1000. Find the product abc.

for b in range(1,500):
c = (- b ** 2 + 1000 * b - 500000)/(b-1000)
a = (c**2 - b**2)**0.5
if (a+b+c) == 1000 and int(a) == a and a > 0:
print a,b,c
print a * b * c
