在python中迭代多维json

import json

def iterate_json(json_data):
    if isinstance(json_data, dict):
        for key, value in json_data.items():
            if isinstance(value, (dict, list)):
                iterate_json(value)
            else:
                # 在这里执行特定的操作，例如打印值或提取特定字段的值
                print(value)
    elif isinstance(json_data, list):
        for index, value in enumerate(json_data):
            if isinstance(value, (dict, list)):
                iterate_json(value)
            else:
                # 在这里执行特定的操作，例如打印值或提取特定字段的值
                print(value)

# 示例JSON数据
json_str = '''
{
  "name": "John",
  "age": 30,
  "address": {
    "street": "123 Street",
    "city": "New York"
  },
  "languages": ["Python", "JavaScript", "Java"]
}
'''

# 将JSON字符串转换为Python对象
json_data = json.loads(json_str)

# 迭代多维JSON数据
iterate_json(json_data)
