      Environment Variables

      The table below lists the Python related environment variables built in the current runtime environment:
      Environment Variable Key
      Specific Value or Value Source
      PYTHONDONTWRITEBYTECODE
      x
      PYTHONPATH
      /var/user:/opt
      For detailed description on the environment variables, see Environment Variables.

      Included Libraries and Usage

      Note:
      For Python 3.7 and later, the platform no longer has additional built-in dependent libraries. For more information on the dependencies required by code execution, see Dependency Installation.

      COS SDK

      SCF's running environment for Python 3.6 and Python 2.7 has integrated the COS SDK. You can introduce and use the COS SDK in your code as follows:
       from qcloud_cos_v5 import CosConfig
       from qcloud_cos_v5 import CosS3Client
      For detailed instructions on usage of the COS SDK, see COS SDK for Python.

      Built-in Libraries

      The table below lists the supported SCF libraries in the Python 3.6 cloud runtime environment.
      Note:
      To use a library not listed here, you need to locally install, package, and upload it. For detailed directions, see Installing Dependent Libraries.
