Geometry insterselect

I want use function geometry all interselect …i can use codeblock with
Autodesk.Geometry.IntersectAll(#A,#B); work

but in python code:
xx= Geometry.IntersectAll(A,B) doesnt work…also I tested a list with A+B
xx= Geometry.IntersectAll©
how can I use this function in python code?
