Write a function that takes an array of numbers (integers for the tests) and a target number. It should find two different items in the array that, when added together, give the target value. The indices of these items should then be returned in a tuple like so: `(index1, index2)`.
For the purposes of this kata, some tests may have multiple answers; any valid solutions will be accepted.
The input will always be valid (numbers will be an array of length 2 or greater, and all of the items will be numbers; target will always be the sum of two different items from that array).
Based on: http://oj.leetcode.com/problems/two-sum/
def two_sum(numbers, target):
    return [[i, numbers.index(target - numbers[i])] for i in range(len(numbers)) if target - numbers[i] in numbers].pop()
def two_sum(numbers, target):
    return [[i, numbers.index(target - numbers[i])] for i in range(len(numbers)) if target - numbers[i] in numbers].pop()
