Even though we have already covered the methods for getting help from CAS, it is an important topic to recap. Every object in the SWAT package uses the standard Python method of surfacing documentation. This includes the help function in Python (for example, help(swat.CAS)), the ? suffix operator in IPython and Jupyter (for example, swat.CAS?), and any other tool that uses Python’s docstrings.

In addition, action sets and actions that are loaded dynamically also support the same Python, IPython, and Jupyter Help system hooks (for example, conn.summary?).

Keep in mind that tab completion on the CAS objects and other objects in the SWAT package can be a quick reminder of the attributes and methods of that object.

These Help system hooks should be sufficient to help you get information about any objects in the SWAT package, CAS action sets, and CAS actions and their parameters. If more detailed information is needed, it is available in the official SAS Viya documentation on the SAS website.
