spython: Singularity/Apptainer Python Client

spython is a Python library that provides a programmatic interface for interacting with the Singularity (now Apptainer) container engine. It allows Python applications to execute Singularity commands, manage images, and run containers without directly calling the command-line interface. The current version is 0.3.15, and it maintains a somewhat active release cadence with several updates per year.
