Example: two sum in python with 0ms runtime

def twoSum(self, nums: List[int], target: int) -> List[int]:        dictionary = {}        answer = []                for i in range(len(nums)):            secondNumber = target-nums[i]            if(secondNumber in dictionary.keys()):                secondIndex = nums.index(secondNumber)                if(i != secondIndex):                    return sorted([i, secondIndex])                            dictionary.update({nums[i]: i})
