It’s much more efficient to simply filter the nodes as you assemble a list:
notViewers = [n for n in nuke.selectedNodes() if n.Class() != 'Viewer']

Subject: [Nuke-python] Re: [Nuke-users] How to get all but one class in
nuke.selectedNodes…?
Your code does nothing to remove anything from your collection. Did you mean
something similar to this:
collection = nuke.selectedNodes()
for n in collection[:]: # use a copy of your list to be able to remove items
from it
if n.Class() == 'Viewer':
n['selected'].setValue(False)
collection.remove(n)
At this point, your viewers are deselected and not part of your collection.
That being said, you mentioned something about them being "connected", but your
code did not address anything with connection. Is this what you were after, or
you really needed something around the connection between nodes and viewers to
be dealt with?
Cheers. nico

Hi,
I can't get my brain to figure this out, so I'm reaching out to the
"collective brain"… 8^)
I need a collection of nodes, minus any connected Viewers. So, selNodes =
nuke.selectedNodes() --- but without any Viewers that may be connected...
I can do this:
selNodes = nuke.selectedNodes()
for node in selNodes:
if node.Class() == 'Viewer':
node["selected"].setValue(False)
else:
node['selected'].setValue(True)
However, that does not change the original collection of nodes - it still has
all of the nodes that were connected when I set the origin variable, including
any Viewers. I want to *remove* any Viewer class nodes from the selNodes
collection!
I know it's probably simple, but it's been a long week… Any help?
Thanks!

"Until one is committed, there is hesitancy, the chance to draw back
ineffectiveness. Concerning all acts of initiative and creation, there is one
elementary rule - the ignorance of which kills countless ideas and splendid
plans; that the moment one definitely commits oneself, then Providence moves
too. Things occur to help that would never otherwise have occurred. A whole
stream of events issues from the choice, raising in one's favour all manner of
unforeseen incidents and meetings and material assistance, which no man could
have dreamed would have come his way."
