I'm not seeing the need for importing string

At this point words would have to be a group of three successive words,
joined with a single space separator. So we can still use your loop
and only print with newline on the last of every group of three. So
we can use a counter to tell where in the cycle we are, e.g., combining
read() and split() and enumerating the split sequence, (untested)
for i, words in enumerate(inp.read().split()):
if i%3 < 2:
print words, # trailing comma makes a space separator if next print
continues line output
else: # do as before and print final word with newline

Upgrade if you don't have 2.4 ;-)
Then you can do a oneliner with a single print ;-)
Set up the data file example:
>>> open('xyplan.nobreaks','w').write("""\
... 3905
... 3009
... 0000
... 4508
... f504
... 0000
... 3707
... 5a07
... 0000
... """)
Show it as is:
>>> print '----\n%s----'%open('xyplan.nobreaks').read()
----
3905
3009
0000
4508
f504
0000
3707
5a07
0000
----
Now the one-liner, FWIW ;-)
>>> print '\n'.join(' '.join(z) for it in [(ln.strip() for ln in
>>> open('xyplan.nobreaks'))] for z in (zip(it, it, it) ))
3905 3009 0000
4508 f504 0000
3707 5a07 0000
