How to sum two numbers in a list in Python?
Given nums = [2, 7, 11, 15], target = 9, Because nums [0] + nums [1] = 2 + 7 = 9, return [0, 1]. use itertools.combinations which combines the elements of your list into non-repeated couples, and check if the sum matches. If it does, print the positions of the terms:
