Is there a way to use itertools in python to clean up nested iterations?

Solution
Use `itertools.product` within a list comprehension:
In [1]: from itertools import product
In [5]: [i*j*k for i, j, k in product(a, b, c)]
Out[5]:
[6,
10,
14,
12,
20,
28,
18,
30,
42,

Problem
Let's say I have the following code: ``` a = [1,2,3] b = [2,4,6] c = [3,5,7] for i in a: for j in b: for k in c: print i * j * k ``` Is there a way I can consolidate an iterator in one line instead of making it nested?
