-Singularity Python is a python module and command line tool for working with <a href="https://singularityware.github.io" target="_blank">Singularity</a> containers, specifically providing functions to visualize, package, and compare containers. Currently, most functions use Singularity on the command line, and some require sudo.

+ - If you are looking for the Singularity Python client to pull, build, and otherwise wrap Singularity functions, then please see the repository [singularity-cli](https://singularityhub.github.io/singularity-cli) for the [spython](https://pypi.org/project/spython/) module.
+ - If you are looking for local management and interaction with various storage locations (e.g., to pull and inspect containers in Singularity Hub, Registry, or other cloud resource) then please see the [Global Client](https://singularityhub.github.io/sregistry-cli) for the `sregistry` module.

+You have the option to install only the dependencies that are needed for your functionality of interest.

+# Metrics and analysis dependencies
+pip install singularity[metrics]
+
+# Building on Google Cloud
+pip install singularity[google[

 We currently require Python > version 3 to use various timezone functions. If you are unable to install version 3.0, we provide a [Singularity.container](Singularity.container) for you to use instead. This is the recommended approach as some older versions of Python do not support generation of the timestamp. See the [installation docs](https://github.com/singularityware/singularity-python/wiki/Installation) for your different options.
