由[JodyZ203](https://github.com/JodyZ0203)提供 1. Two Sums Python3 解法代码:
;; 只用一个哈希表
'''Python
class Solution:
def twoSum(self, nums, target):
"""
:type nums: List[int]
:type target: int
:rtype: List[int]
"""
# 提前构造一个哈希表
hashTable = {}
# 寻找两个目标数值
for i, n in enumerate(nums):
other_num = target - n
# 如果存在这个余数 other_num
if other_num in hashTable.keys():
# 查看是否存在哈希表里,如果存在的话就返回数组
return [i, hashTable[other_num]]
# 如果不存在的话继续处理剩余的数
hashTable[n] = i
