is it possible to set point vector/float/int array attributes with python in geometry module? Im using houdini 17.0.502 version. there are floatList methods for global attributes in geometry module but no such things for points

yes.
node = hou.pwd()
geo = node.geometry()

newValue = 1
for point in geo.points():
    point.setAttributeValue('attributeName',newValue)

you can access the points and use the setAttributeValue method to give them a new attribute. The code above iterates through all points in the geometry and sets their value to 1.

if you need to access individual faces/prims you have to get at the points a little differently by getting the vertex first something like
prims = geo.prims()
for prim in prims:
    verts = prim.vertices()
    for vert in verts:
        point = vert.point()
        point.setAttributeValue('attributeName',newValue)

I know the iteration ways and I dont want to use them as they are slow when dealing with heavy meshes. thats why the geometry module. I can set all other attribute types in geometry module except point/prim arrays. is this just left out from python implementation?
