if you use tcl (stuff inside and including the square brackets) inside a
file path in Nuke, it will be calculated on the fly.
So you can use python to construct a file path which includes a valid
tcl command, then assign the lot via python.
Nuke will then carry on doing what it does anyway, which is evaluate the
TCL on the fly.
For Python, it's just a string either way.

Thanks Frank, this would be for a tcl script button i'm assuming?
what if the button was a python button?

Sure. Just use something like this to generate your Read node:
path/to/file/*[value NoOp1.whichsheet]*/*[value NoOp1.chooseread]*

Thanks Frank, that lind of works for what i'm trying to do..
here's what i'm trying to do, im simpler form (all made on no-op).
essentially, i've got a bunch of elements, then trying to select the
parent directory of certain elements, then select the filename and
then finally, read in said element..
set cut_paste_input [stack 0]
version 10.0 v3
push $cut_paste_input
NoOp {
name NoOp1
selected true
xpos -798
ypos -669
addUserKnob {20 User}
addUserKnob {4 whichsheet l "parent directory" M {glass elements "" ""}}
addUserKnob {4 chooseread l "read in" M {glass.png fuzz.png red.png}}
addUserKnob {22 readthis l read T "thisNode =
nuke.thisNode()\n\n#check whether gizmo inside group\nroot =
'root'\nnodeRoot = thisNode.fullName()\nif nodeRoot.count('.') >
0:\n root = '.'.join(nodeRoot.split('.')\[:-1])\n\nwith
nuke.toNode(root):\n #create read\n
nuke.nodes.Read(file=\"path/to/file/glass.png\")" +STARTLINE}

if i want to create a read node based on what is selected in a
pulldown menu, how would i do that?
say my menu has the following two files listed..
aura_green.png
bluesky.png
redball.png
i can create a read by adding..
nuke.nodes.Read(file="/home/darren/Pictures/aura_green.png")
which only links directly to the file listed, but i'd like it to
change the filename depending on whats selected in the pulldown menu.
Thanks.
Darren
