Can you correct my code, please?

Question

#two sum problem from leetcode.com
#Description:
Given an array of integers, return indices of the two numbers such that they add up to a specific target.

You may assume that each input would have exactly one solution, and you may not use the same element twice.

Example:

Given nums = [2, 7, 11, 15], target = 9, Because nums[0] + nums[1] = 2 + 7 = 9, return [0, 1].
#my code:

def twoSum(self, nums: List[int], target: int) -> List[int]:
l = len(nums)
for i in range(l):
s = sum
for j in range(l):
s = sum([nums[i], nums[j]])
if s == target and i != j:
return [j, i]

Answer 1

Your code returns indecies, not values. Fixed that. Also made sure that you get an input from server or user. Not sure if that was part of a problem.
Other than that, the overall logic looks fine.

Here is a modified code:

Answer 2

s = sum?

Answer 3

My code doesn't pass "Submit" on leetcode.com problems. I guess this code doesn't work in all cases.
