Using GetDependentElements Method

Hi would like to use the GetDependentElements Method From PartMaker Class

The get dependent elements method recives a filter

the ElementClassFilter Constructor recives a type to do a filter of this type (I Think)

And to create this type I would need to import the type class (from .net?)

And I also have to put the return of the method in a IList

The ref would look something like this ?

from System.Collections.Generic import List
from System import Type

And the code would look something like this ?

Part_type=typeof(part)#making the part type
filter=ElementClassFilter(Part_type)#making the filter#making the filter
Part_List=List[ElementId]()#making the part list receiver
PartList.Add(GetDependentelElements(filter)) #getting parts ids 

If anyone could help, I would appreciate
