如评论中所述，

As mentioned in the comments, the not accepted answer in the linked question works perfectly fine for you case:

data = {
  "results": [
    {
      "Fruit": "Apple",
      "Nested fruit": [
        "Orange"
      ],
      "Title1": "Some text",
      "Contents": {
        "Name 1": [ 
          "John Smith"
        ],
        "Name 2": [
          "Tyler"
        ],
        "Name 3": [
          "Bob",
          "Rob"
        ],
        "Name 4": [
          "Linda"
        ],
        "Name 5": [
          "Mark",
          "Matt"
        ],
        "Some boolean": [
          True
        ]
      },
      "More stuff": "More random text",
      "Confusing": [
        {
          "Some info": "456",
          "Info I want": "849456"
        }
      ],
      "Not important": [
        {
          "random text": "bla",
          "random text2": "bla bla"
        }
      ],
      "Not important 2": "000",
      "Not important3": [
        "whatever",
        "whatever"
      ],
      "Not important 4": "16",
      "Not important 5": "0058"
    }
  ]
}


def item_generator(json_input, lookup_key):
    if isinstance(json_input, dict):
        for k, v in json_input.items():
            if k == lookup_key:
                yield v
            else:
                yield from item_generator(v, lookup_key)
    elif isinstance(json_input, list):
        for item in json_input:
            yield from item_generator(item, lookup_key)


res = item_generator(data, 'More stuff')
print([x for x in res])

res = item_generator(data, 'Info I want')
print([x for x in res])

输出:

['More random text']
['849456']
