如何通过 Python SDK 获取 Collection 列表

Client.list() -> DashVectorResponse

import dashvector
client = dashvector.Client(    api_key='YOUR_API_KEY',    endpoint='YOUR_CLUSTER_ENDPOINT')
collections = client.list()
# 判断list接口是否成功if collections:    # 查看所有collections    for collection in collections:        print(collection)
    # collections长度    print(len(collections))
    # 判断某个collection是否存在    print('YOUR_COLLECTION_NAME' in collections)else:    # 若获取失败，打印错误信息    print(collections)
