python 支持循环内的递归函数

Question

我是 Python 编码的初学者，希望得到您的支持。我正在编写代码来创建具有父子关系的嵌套字典。该程序以 API Rest 调用开始，在一个循环中需要提取所有子项，而新循环中的每个子项都需要提取另一个子项。我在第二个循环中遇到了一些挑战，因为每次完成递归调用时，我都会丢失我的 for 循环引用。

下面的代码示例 谢谢

def add_keys_nested_dict(dictionary, keys):

    if len(keys) == 1:

        dictionary.setdefault(keys[0], {})

    else:

        key = keys[0]

        if key not in dictionary:

            dictionary[key] = {}

        add_keys_nested_dict(dictionary[key], keys[1:])

def getChild(data,i,dictionary,flag,child_id,depth):
        
       #if 'attributes' in data and 'children' in data and 'name' in  data['attributes'] and len(data['children'])==0:
       depth=int(depth)
       if depth != 0:                        
               #for b in range(len(data['children'])):

我尝试编写一个递归函数但是不起作用
