如何搜索嵌套字典而不关心顶级关键字

def search_nested_dict(nested_dict, keyword):
    result = []
    for key, value in nested_dict.items():
        if key == keyword:
            result.append(value)
        elif isinstance(value, dict):
            result.extend(search_nested_dict(value, keyword))
    return result

nested_dict = {
    'key1': 'value1',
    'key2': {
        'key3': 'value2',
        'key4': {
            'key5': 'value3'
        }
    },
    'key6': 'value4'
}

result = search_nested_dict(nested_dict, 'key5')
print(result)  # 输出: ['value3']
