# `ListFlowAliases` 搭配 AWS SDK 使用
<a name="bedrock-agent_example_bedrock-agent_ListFlowAliases_section"></a>

以下程式碼範例顯示如何使用 `ListFlowAliases`。

------
#### [ Python ]

**適用於 Python 的 SDK (Boto3)**  
 GitHub 上提供更多範例。尋找完整範例，並了解如何在 [AWS 程式碼範例儲存庫](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/python/example_code/bedrock-agent#code-examples)中設定和執行。
列出 Amazon Bedrock 流程的別名。  

```
def list_flow_aliases(client, flow_id):
    """
    Lists the aliases of an Amazon Bedrock flow.

    Args:
        client: bedrock agent boto3 client.
        flow_id (str): The identifier of the flow.

    Returns:
        dict: The response from ListFlowAliases.
