Python提取目标Json键值：包含子嵌套列表和字典

目标：取json中所有的Name、Age字典

思路：递归处理字典中直接包含子字典的情况，

import jsondef find_targ_dicts(data,key1,key2):result = {}if isinstance(data, dict):if key1 in data and key2 in data: # 第一层字典中包含key1和key2result[key1] = data[key1]result[key2] = data[key2]yield resultfor k, v in data.items():yield from find_targ_dicts(v, key1, key2) # 递归处理子字典elif isinstance(data, list):for item in data:yield from find_targ_dicts(item, key1, key2)# 示例JSON数据
json_data = '''
{"name": "mkdm","age": 30,"children": [{"name": "Ace","age": 10},{"name": "Bob","age": 8},{"tt":{"name": "coh","age": 9}}],"address": {"city": "shbj","addr": "sccd"}
}
'''# 将JSON字符串转换为Python对象
data = json.loads(json_data)# 提取所有的字典
dicts = list(find_targ_dicts(data,'name','age'))
print(dicts)
# 打印所有的字典
for d in dicts:print(d)
