**如何打印返回index1,index2？我尝试了不同的方法，但没有打印出任何内容。**

class Solution:
    def twoSum(self, nums, target):
        nums = [2,7,11,15]
        target = 9
        hash_map = {}
        for index, value in enumerate(nums):
            hash_map[value] = index
        for index1, value in enumerate(nums):
            if target - value in hash_map:
                index2 = hash_map[target - value]
                if index1 != index2:
                    return [index1,index2]

                if index1 != index2:
                    return [index1,index2]

if __name__ == '__main__':
    print(Solution().twoSum(9, [2,7,11,15]))

我认为您正在寻找的是一个 main 函数，您可以在其中使用您的函数
