Not really. It seems to rely on list(set(...)) kinda randomizing order... w=
hich is definitely not safe without hash randomization. =20

But this brings up an interesting concept... if we can assume Python 2.7 wi=
th the -R flag, or Python 3.3+, I think we do get true pseudo-randomization=
 out of list(set(...))... which means we can trim some!

print(list(set(open('/usr/share/dict/words')))[:4])

No module imports needed! Although it's not as pretty as the original post,=
 but neither was Roy's.
