ok, cool, I think I understand it better now. Thanks, guys. Also, if you
don't mind, another question, what exactly is the '%' doing in this
code. And I have used 'int' before, and seen the '16' posted around,
what exactly are those doing, I am guessing that is what converts the
value from string to integer?

The problem isn't hex vs. int; the value you're getting back from the
Python knob is identical to the hex value returned by the nuke.tcl
call. The issue you're running into is that the nuke.tcl call is
returning the hex value as a string, so you need to cast it to a
numeric type before you can actually use it.
n = nuke.selectedNode()
tile_color = int(nuke.tcl('value [topnode %s].tile_color' % n.name()), 16)

Thanks Ivan.
This was pretty much exactly what I was looking for. However I had to
change it a little bit because this was returning the tile color hex
value, if I understand all this correctly, and my function needs just
the integer value. As I can't assign or set a tile_color using hex, or
I haven't been able to figure it out.
Anyways, for whatever reason this does the trick, kinda mixing your
code with what I had before. I am still not very sure why the
tile_color has 2 different value formats.
n = nuke.selectedNode()
topnode_name = nuke.tcl("full_name [topnode %s]" % n.name())
topnode = nuke.toNode(topnode_name)
tile_col = topnode['tile_color'].value()
Thanks again and much appreciated.

tile_color of the top node, you could of course do:
n = nuke.selectedNode()
tile_color = nuke.tcl("value [topnode %s].tile_color" % n.name
<http://n.name>())
Hope that helps

You can use nuke.tcl() within python to execute a tcl command.
So, in your case, something like this should work:
n = nuke.selectedNode()
topnode_name = nuke.tcl("full_name [topnode %s]" % n.name
<http://n.name>())
topnode = nuke.toNode(topnode_name)

Hopefully a quick question,
If I currently have a node selected somewhere in a tree, and I want to
access the topnodes tile color using python, how would I do so? Using
[[topnode].tile_color] doesn't seem to work as it is tcl? Looking
around it seems you need to check dependecies of all the nodes or
something, but I haven't been able to get anything to work. Is there
no way to convert the tcl function to work in python?
Thanks in advance for any help,
Adam
