I'm trying to figure out how to find the primitive group with the largest amount of primitives in it. Is there a Python function for querying primitive counts of primitive groups? I would expect there to be since you get the prim group list and number of primitives when you middle mouse click on a node.
As a start I tried getting a list of primitives from my node: hou.hscriptExpression(primgrouplist(“/obj/geo1/partition1”))
That didn't seem to work too well.
Anyone have any pointers on how to approach this?
Query amount of primitives in a primitive group?

Thanks Peter,
I took a little while, but I finally got a method that works:
p = ‘primgrouplist(“/obj/geo1/partition1”)’
t = hou.hscriptExpression(p)
items = t.split()
d1 = {}
for i in items:
r = ‘primlist(“/obj/geo1/partition1”,’+ i +')'
c = hou.hscriptExpression(r)
primcount = len(c.split())
d1 =
hiCount_primGroup = max(d1, key=lambda x: d1)
Probably the biggest pain was figuring out the syntax for using hscript expressions in Python.
Still easier than doing it by hand for
1500 objects though!

Yeah, to be honest I still use Hscript for all expression work, but Python for more general scripting. Thanks for posting this though, it helps me think about it Pythonically too
One thing I'm a bit concerned about is speed of Hscript vs Python especially if you're running the expression in a node's Parameter. My initial tests (admittedly a year ago) showed Hscript about 3x faster, but like I said, I haven't tested it recently.
Cheer,s
