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

以下程式碼範例顯示如何使用 `ListFlows`。

------
#### [ 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。  

```
def list_flows(client):
    """
    Lists versions of an Amazon Bedrock flow.

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

    Returns:
        Nothing.
    """
    try:
        finished = False

        logger.info("Listing flows:")

        response = client.list_flows(maxResults=10)

        while finished is False:

            for flow in response['flowSummaries']:
                print(f"ID: {flow['id']}")
                print(f"Name: {flow['name']}")
                print(
                    f"Description: {flow.get('description', 'No description')}")
                print(f"Latest version: {flow['version']}")
                print(f"Status: {flow['status']}\n")

            if 'nextToken' in response:
                next_token = response['nextToken']
                response = client.list_flows(maxResults=10,
                                             nextToken=next_token)
            else:
                finished = True

        logging.info("Successfully listed flows.")


    except ClientError as e:
        logging.exception("Client error listing flow versions: %s", str(e))
        raise
    except Exception as e:
        logging.exception("Unexpected error listing flow versions: %s", str(e))
        raise
```
