如何從包含字典列表的字典中獲取項目

Question

我有包含字典列表的字典：

dict = {"key0": "some_value", "key1": 1, "value": [{"key2": "some_value", "key3": "some_value", "key4": {"key5": 0}, "key6": {"key7": {"key8": "some_value", "id": "some_id"}, "key9": {"key10": "some_value", "id": "some_id_2"}}}]}

我正在努力尋找獲取“id”字段的方法，以防我發現“key7”或“key9”存在。 就像是：

for key in dict.items(): 
    if 'value' in dict.keys(): 
        if 'key7' in dict.values(): 
            print("I want to print key7 id value here") 

預期 output： some_id

如果有人會遇到這種情況，請找到一種訪問項目的方法：

my_dict = {"key0": "some_value", "key1": 1, "value": [{"key2": "some_value", "key3": "some_value", "key4": {"key5": 0}, "key6": {"key7": {"key8": "some_value", "id": "some_id"}, "key9": {"key10": "some_value", "id": "some_id_2"}}}]}

然后是這樣的：

for k, v in my_dict.items(): 
    if isinstance(v, list): 
        value_list = v 
        if not value_list: 
            pass 
        elif value_list is not None: 
            for vl in value_list: 
                print(vl['key6']['key7']['id']) 
                print(vl['key6']['key9']['id'])

它遍歷字典，直到字典的值是列表，然后如果值是列表，使用列表理解，您可以訪問元素，它將 output：

some_id
some_id_2
