how to sum two numbers in a list?

Question

what is the solution of this by python 3 ?

Given an array of integers, return indices of the two numbers such that they add up to a spe

Answer 1

For each entry in the list, check whether there's any other numbers in the list after that number that add up to the target. Since a+b = target is equivalent to b = target - a, you can just take each element, look at all the numbers after that element, and check whether they are target - element. If so, return the indices.

for index,num in  enumerate(nums):
    if target-num in nums[index+1:]:
        return(index, nums.index(target-num))
