  from qcloud_cos_v5 import CosConfig 
  from qcloud_cos_v5 import CosS3Client

• For the cos_sdk_v4 version:

  import qcloud_cos

  from qcloud_cos_v4 import CosClient
  from qcloud_cos_v4 import DownloadFileRequest
  from qcloud_cos_v4 import UploadFileRequest

For more detailed instructions on how to use the COS SDK, see COS SDK for Python.
