如何计算字典列表中特定字典键的出现次数，一些字典值包含列表和 append 计数值

Question

我正在尝试计算指定键在我的dict list中出现的次数。 我已经使用循环和求和来计算所有键的数量，但如何找到特定键的计数？ 我有这段代码，目前不起作用：

for dico in data:
    for ele in dico['people']:
                  print(ele['name']+str(len(ele['animals'])))

“条目”数据如下所示：

[
  {
    "name": "Uzuzozne",
    "people": [
      {
        "name": "Lillie Abbott",
        "animals": [
          {
            "name": "John Dory"
          }
        ]
      }
    ]
  },
  {
    "name": "Satanwi",
    "people": [
      {
        "name": "Anthony Bruno",
        "animals": [
          {
            "name": "Oryx"
          }
        ]
      }
    ]
  },
  {
    "name": "Dillauti",
    "people": [
      {
        "name": "Winifred Graham",
        "animals": [
          { "name": "Anoa" },
          { "name": "Duck" },
          { "name": "Narwhal" },
          { "name": "Badger" },
          { "name": "Cobra" },
          { "name": "Crow" }
        ]
      },
      {
        "name": "Blanche Viciani",
        "animals":
          [{ "name": "Barbet" },
          { "name": "Rhea" },
          { "name": "Snakes" },
          { "name": "Antelope" },
          { "name": "Echidna" },
          { "name": "Crow" },
          { "name": "Guinea Fowl" },
          { "name": "Deer Mouse" }]
      }
    ]
  }
]

我的目标是通过计算孩子的数量并将其附加到名称中来打印人和动物的数量，例如。 Satanwi [2] 。

[ { name: 'Dillauti [5]',
    people:
     [ { name: 'Winifred Graham [6]',
         animals:
          [ { name: 'Anoa' },
            { name: 'Duck' },
            { name: 'Narwhal' },
            { name: 'Badger' },
            { name: 'Cobra' },
            { name: 'Crow' } ] },
       { name: 'Blanche Viciani [8]',
         animals:
          [ { name: 'Barbet' },
            { name: 'Rhea' },
            { name: 'Snakes' },
            { name: 'Antelope' },
            { name: 'Echidna' },
            { name: 'Crow' },
            { name: 'Guinea Fowl' },
            { name: 'Deer Mouse' } ] },
      ...
...
]

这会做你想做的； 随时询问您是否需要解释：

for dico in data:
    children = 0
    for ele in dico['people']:
        animals = len(ele['animals'])
        children += 1 + animals
        ele['name'] += f" [{animals}]"
    dico['name'] += f" [{children}]"
