      Included Library and Usage

      COS SDK

      SCF's runtime environment already contains the COS SDK for Python, and specific versions are cos_sdk_v5 (recommended) and cos_sdk_v4.
      The COS SDK can be referenced and used within the code as follows:
      For the cos_sdk_v5 version:
      import qcloud_cos_v5
      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.
