【问题描述】：

我有一个高度嵌套的 JSON 对象。有没有一种方法可以查看分层树形图？我浏览了几个资源，如 Pydot、Plotly 等，但没有什么能以我的格式呈现 JSON。

JSON 文件：

更准确地说，我想提取每个级别的平均分支数。

预期结果是：

Level 0: 4  
Level 1: (1 + 2 + 1 + 1)/4  
Level 2: 0

    【解决方案1】：

    尚不完全清楚您要做什么，但以下代码计算了每个嵌套深度的字典和列表的数量。我们使用collections.deque 作为堆栈来执行广度优先搜索，计算每个级别的嵌套容器的数量，将计数存储在列表的defaultdict 中，并将这些容器推入堆栈以供将来处理。当我们计算完所有对象后，我们计算每个级别的平均分支数。

    我不会将您的数据粘贴到这段代码中，因为它大约有 740 行长。我将该数据称为data_string，在我的机器上我只是将您的数据用三引号括起来，但当然您可以将其保存为文件，然后使用json.load 加载它。

    import json
from collections import defaultdict, deque

data = json.loads(data_string)

def get_branches(obj):
    branches = defaultdict(list)
    stack = deque()
    stack.append((obj, 0))
    while stack:
        obj, depth = stack.pop()
        newdepth = depth + 1
        branch_count = 0
        if isinstance(obj, dict):
            obj = obj.values()
        for child in obj:
            if isinstance(child, (list, dict)):
                branch_count += 1
                stack.append((child, newdepth))
        if branch_count:
            branches[depth].append(branch_count)
    return branches

branches = get_branches(data)
for depth in sorted(branches.keys()):
    row = branches[depth]
    mean = sum(row) / len(row) if row else None
    print('Level', depth, row, mean)

    输出

    Level 0 [2] 2.0
Level 1 [4, 1] 2.5
Level 2 [5, 5, 5, 5] 5.0
Level 3 [3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3] 3.0
Level 4 [1, 1, 1, 2, 1, 1, 1, 1, 2, 1, 1, 1, 1, 2, 1, 1, 1, 1, 2, 1] 1.2
Level 5 [3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3] 3.0

    【讨论】：

    • 感谢您的回答。有没有办法让我得到整个 json 的哪一部分属于相应的级别？一个这样的例子是不言自明的。
    • @nikinlpds 这听起来像是一个新问题的好话题。 ;) 如果需要，您可以在新问题中添加一个链接回到这个问题。你需要准确地解释你想如何衡量它。我假设你想要它的节点（项目）数量，但也许你想用字符来衡量它。
    • 感谢您的快速回复。基本上，必须获取遍历时落在每个级别中的 JSON 的任何部分。我在这里提出了一个单独的问题 - stackoverflow.com/questions/51189250/…。我最终要做的是查看每个级别中存在多少与“概念”相对应的元素。
    • @nikinlpds 正如布鲁诺所说，您需要更清楚地解释您的问题，否则它将被搁置。
    • 好的。我会让它更简单。目前，我们计算了每个嵌套深度的字典和列表的数量。我只希望按级别提取整个字典/列表。现在清楚了吗？
