.value() is the literal value of the knob (i.e. what it's storing). It
doesn't expand TCL expressions, frame numbers, view tokens, etc.
.evaluate() is the result of evaluating the knob's literal value within the
current context.

Subject: Re: [Nuke-python] Re: ['autolabel'].value()
There's maybe more differences, but it doesn't expand %04d file numbers,
only "[tcl ...]" stuff:
_>>> r = nuke.nodes.Read()
_>>> r['file'].setValue("[expr 1234*2].%04d.exr")
_>>> r['file'].value()
'[expr 1234*2].%04d.exr'
_>>> r['file'].evaluate()
'2468.0000.exr'
_>>> nuke.tcl('subst', r['file'].value())
'2468.%04d.exr'

The Foundry are using something this instead:
user_label = nuke.value("size")
user_label = nuke.tcl("subst", user_label)
Anyone know the difference between that and evaluate()? They both seem
to do the same thing.
Thanks

solution use evaluate() i.e.
user_label = tn['label'].evaluate()
