QueryInterface

Queries the object for an interface. 

Comments

Note that there are no reference counting functions that are typically exposed via COM. This is because COM reference counts are automatically handled by PythonCOM - each interface object keeps exactly one COM reference, regardless of how many Python references. When the Python object destructs due to its reference count hitting zero, the COM reference is then released. It is not possible for force the closure of a PythonCOM object - the only way to ensure cleanup is to remove all Python references.
