A long way to do this is as follows (you've already been shown the short 
way using permutations)

words = ['salem','Ali','sultan']

for a in words:
    for b in words:
         if b != a:
              for c in words:
                  if c != a:
                      if c != b:
                          print [a, b, c]

Not quite so long:

words = ['salem','Ali','sultan']

for a in words:
    for b in [x for x in words if x != a]:
        for c in [x for x in words if x != a and x != b]:
            print [a, b, c]

Observe that neither of these scale as elegantly as the permutations 
example already given.
