get group number in group pattern

[luoqiulin]

when i use python

>>>a = hou.node("obj/grid_object1/group1").evalParm('pattern')

>>>a

'40 50-52 60-63 70-74 80-85 90-95 '

how can i change the it like this?

'40 50 51 52 60 61 62 63 70 71 72 73 74 80 81 82 83 84 85 90 91 92 93 94 95

If you're using hscript, you can use the pointpattern expression to do this, so:

pointpattern("obj/grid_object1/group1", "40 50-52 60-63 70-74 80-85 90-95")

will yield the series of individual point numbers.

In Python you can do it with hou.Geometry.globPoints then turn the point numbers in to a string, if that's what you need, so something like:

n = hou.node("obj/grid_object1/group1")
pattern = n.evalParm('pattern')
pts = n.geometry().globPoints(pattern)
return " ".join(str(pt.number()) for pt in pts)

Something along those lines should work, I think.
