This is described in the Python language binding:

Operations of an interface map to methods available on the object references.
Parameters with a parameter attribute of in or inout are passed from left to
right to the method, skipping out parameters. The return value of a method
depends on the number of out parameters and the return type. If the
operation returns a value, this value forms the first result value. All
inout or out parameters form consecutive result values. The method result
depends then on the number of result values:

* If there is no result value, the method returns None.
* If there is exactly one result value, it is returned as a single value.
* If there is more than one result value, all of them are packed into a
  tuple, and this tuple is returned.
