AWS code-library documentation change

Service: code-library · 2025-06-28 · Documentation low

File: code-library/latest/ug/neptune_example_neptune_DeleteDBSubnetGroup_section.md

Summary

Added Python (Boto3) code example for DeleteDBSubnetGroup with error handling for AccessDeniedException and DBSubnetGroupNotFoundFault

Security assessment

The change adds standard API usage documentation with error handling. While it mentions AccessDeniedException, this is routine permission checking rather than addressing a specific security vulnerability. No evidence of patching a security issue or introducing new security features.
