This should do the trick.
first = nuke.Root()['first_frame'].value()
last = nuke.Root()['last_frame'].value()
frame = nuke.frame()
if frame in [first, last]:
ret = 1
else:
ret = 0

Hi all,
Anyone knows an expression to to switch in the switch node from 0 to 1
on 1st & last frame?
let's just say I want the switch node to be 1 at 1st & last frame & 0
for the rest of the seq.
I tried first_frame!=1 but it doesn't switch.
Thanks in advance,
