如何在嵌套字典中 select 元素并递归删除它们

我已经生成了一个嵌套字典作为 JSON ，其中包含一个概念，然后在从网站或不同的 JSON （称为“ALTERNATIVE”）抓取的句子中引用该概念，并具有关联的超类（请参阅超链接和下面的实际最小值可行的例子）：

"Glide": {"superclasses": {"Entity": [{"source": "ALTERNATIVE"}]}}, "Yacht": {"superclasses": {"Boat": [{"reference": "Originally, yachts were sailing-boats, but now there are also motor yachts.", "source": "https://simple.wikipedia.org/wiki/Yacht"}, {"reference": "A yacht is a type of boat which is mainly used for recreation.", "source": "https://simple.wikipedia.org/wiki/Yacht"}], "Vessel": [{"reference": "In sailboat racing, a yacht is any sailing vessel taking part in a race.", "source": "https://simple.wikipedia.org/wiki/Yacht"}]}}, "Yam": {"superclasses": {"Vegetable": [{"reference": "A yam is a root vegetable.", "source": "https://simple.wikipedia.org/wiki/Yam"}, {"reference": "Yam is a vegetable that can be cooked in many ways.", "source": "https://simple.wikipedia.org/wiki/Yam"}], "Name": [{"reference": "Yam is the common name for some species in the genus Dioscorea.  ", "source": "https://simple.wikipedia.org/wiki/Yam"}]}},

我想为嵌套字典中的键（例如“Yacht”）做的是查看它的“超类”（例如在本例中为“Boat”和“Vessel”）并查看它们是否是键我的嵌套字典。

目前，我已将嵌套字典转换为“（键，超类）”形式的元组列表，该列表按照每个键有多少超类（按降序排列）进行排序，以使事情变得更容易。

    import json
    from nltk.corpus import wordnet as wn
   
    
    ## importing the nested dictionary
    tax = json.load(open("data/nested_dict.json"))
    
    ## Converting our nested dictionary into a list of tuples
    tax_list = [(key, value) for key, value in tax.items()]
    
    ## Sorting out list with tuples in descending order of how many superclasses they have
    tax_list.sort(key=lambda x: len(x[1]["superclasses"].keys()), reverse = True)

谢谢，

# Get all Keys in Master Dictionary and Convert to a LIST
allKeys = tax.keys()
allkeys = list(allkeys)  # Convert to a 'list' data structure so you can check it in one line of code (see below)

# I assume you want the user to specify the key in question
myKey = input("Please input key: ")

# Get the Superclass Dictionary Associated with that Specific Key
superClassDictionary = tax[myKey]

# Iterate through the Keys in the superClassDictionary
for superclass in superClassDictionary.keys():
  if superclass in allKeys:
     print("Superclass {} of key {} is also a key in the master dictionary".format(superclass, myKey))
