创建在复杂的嵌套对象和数组中找不到的值数组的简洁方法

def find_value(obj, target):
    if isinstance(obj, dict):
        for key, value in obj.items():
            if key == target:
                return value
            elif isinstance(value, (dict, list)):
                result = find_value(value, target)
                if result is not None:
                    return result
    elif isinstance(obj, list):
        for item in obj:
            if isinstance(item, (dict, list)):
                result = find_value(item, target)
                if result is not None:
                    return result
    return None
