projecteuler---->problem=9----Special Pythagorean triplet

title:

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.

翻译：

勾股数组就是三个自然数a, b, c：

a2 + b2 = c2 (a < b < c)

比如，32 + 42 = 9 + 16 = 25 = 52。

现存在唯一的勾股数组a, b, c，且a + b + c = 1000。请求出这三个数的乘积。

def resu():
	for i in range(1,1000):
		for j in range(1,1000):
			k=1000-i-j
			if i*i+j*j==k*k:
				print i*j*k
				return
resu()
