如何向用户输出与数组中的最大值相关的附加信息？

def output_max_info(arr):
    max_value = float('-inf')
    max_index = -1
    max_count = 0
    max_neighbors = []

    for i in range(len(arr)):
        if arr[i] > max_value:
            max_value = arr[i]
            max_index = i
            max_count = 1
            max_neighbors = []

        elif arr[i] == max_value:
            max_count += 1

        if i > 0 and i < len(arr) - 1:
            if arr[i-1] == max_value or arr[i+1] == max_value:
                max_neighbors.append(arr[i])

    print("最大值：", max_value)
    print("最大值的索引：", max_index)
    print("最大值的出现次数：", max_count)
    print("最大值的相邻元素：", max_neighbors)

# 示例输入
arr = [1, 5, 3, 7, 5, 9, 5, 2, 5]
output_max_info(arr)

最大值： 9
最大值的索引： 5
最大值的出现次数： 1
最大值的相邻元素： [7]
