Looks fine.
The problem with your previous attempt was that using quoted around "f"
means literally the letter f, rather than referring to the variable f
you created earlier.
By using str() you cast the value of the variable f to be a string, e.g.
123 turns into "123", which is what the frame knob expects (unfortunately).

Answering my own question I hope ...
r = nuke.Root()
f = r.knob('first_frame').value()
n = nuke.selectedNode()
print n['frame'].setValue(str(f))
Seems to get me the result I was hoping for - anyone see any problems in this ?
Thx

It tells me it's expecting a string not a float - I guess maybe
that's because I can type expressions in there like "frame/2" do I
need to mangle a float into a string maybe ?

Does it work if you take 'f' out of the 'quotes'? So: print
n['frame'].setValue(f)

Trying to do the simplest thing for days now but still failing.
I want to set a selected Read node knobs "expr" and "frame" to
"start at" and "nuke.Root.first_frame()" so when I get file
frame nos such as 103094 - 103122 I can set the to some "human
useable" range.
Failing on the second part ...
r = nuke.Root()
f = r.knob('first_frame').value()
n = nuke.selectedNode()
print n['frame'].setValue('f')
This sets "frame" to "f" even though
print r.knob('first_frame').value()
Returns a Number "101" for example...
Anyone help me out here - I'm sure it's my basic lack of code knowledge ?
Thx
