Resumen
Lists the versions in the workspace.
Debate
You can specify the path to a connection file as an argument to the function or you can set the workspace environment to the connection file and call the ListVersions function without any arguments.
Nota:
The arcpy.da.ListVersions function should not to be confused with the arcpy.ListVersions function which is used to return a list of version names the connected user has permission to use.
