   HugeGraph 的图空间(graphspace)功能可以实现数据隔离,支持在同一服务下创建多个逻辑空间。你在 PyHugeClient 
初始化时,`graphspace` 参数不仅可以用 "DEFAULT",也可以用你在服务端已创建的其他图空间名。
   
   关键点如下:
   
   1. **服务端先创建图空间**:需要先通过 HugeGraph 的 REST API 创建自定义 graphspace(如 
`testspace`),否则客户端指定会报错。创建 graphspace 的 API 路径一般为 `/graphspaces`,需要带上 
graphspace 名称和创建者等信息,具体可参考 REST API 文档或如下例子:
      ```bash
      curl -X POST "http://<host>:<port>/graphspaces" \
           -H "Content-Type: application/json" \
           -d '{"name": "testspace"}'
      ```
      创建后可通过 `/graphspaces/{graphspace_name}/graphs` 等接口管理该空间下的图。
   
   2. **客户端使用自定义 graphspace**:PyHugeClient 的 `graphspace` 参数可以直接填写你创建的 
graphspace 名称。例如:
      ```python
      client = PyHugeClient(
          "192.168.102.19",
          "58080",
          user="admin",
          pwd="admin",
          graph="hugegraph",
          graphspace="testspace",  # 这里换成你的 graphspace 名称
      )
      ```
      只要服务端存在该 
graphspace,所有操作都会路由到对应空间,实现数据隔离。[相关代码实现](https://github.com/apache/incubator-hugegraph-ai/blob/52a666efabc879d704edc6aad3837358b2d486c1/hugegraph-python-client/src/pyhugegraph/client.py#L36-L58)
   
   3. **API 路径变化**:v3 及以上版本的 HugeGraph,所有 REST API 路径都需要带上 graphspace,例如 
`/graphspaces/{graphspace}/graphs/{graph}/graph/vertices`,这样每个 graphspace 
下的图和数据完全隔离。[API 路径示例](https://github.com/apache/incubator-hugegraph/pull/2894)
   
   4. **注意事项**:PyHugeClient 只负责请求路由,不负责 graphspace 的创建和管理。你需要确保 graphspace 
已在服务端创建好,否则会报空间不存在的错误。[服务端 graphspace 
管理实现](https://github.com/apache/incubator-hugegraph/pull/2900)
   
   如需进一步操作(如列出所有 graphspace、删除 graphspace),请参考 HugeGraph 的 REST API 文档或源码。
