Hi Dave,

Unfortunately, the Python API has not been wired to create new containers.

At the moment, the only documented APIs that have the means to create new containers are the Javascript API and the Java API:

https://www.labkey.org/download/clientapi_docs/javascript-api/symbols/LABKEY.Security.html#.createContainer
https://www.labkey.org/download/clientapi_docs/java-api/org/labkey/remoteapi/security/CreateContainerCommand.html

Regards,

Jon
