The sets module is no longer needed, as we have the built-in sets
type. Its even getting a literal syntax soon.
As for the original problem, I agree on the homework smell.

Hi everyone,
I'm studying python via the excellent "how to think like a python
programmer" book by Allen Downey. Noob question follows...
I have a txt file (animals.txt) which contains the following text
each
on a separate line: aardvark, bat, cat, dog, elephant, fish,
giraffe,
horse, inchworm, jackelope
I want to create a function that loops through the animals.txt file
and does *not* print the word if any of the user specified
letters are
in that word.
def hasnolet(x):
Hope this wasn't a homework assignment... It gave me my
first excuse
to try the set module...
import sets
words = [ "aardvark", "bat", "cat", "dog", "elephant", "fish" ]
exclude = "want"
excludeset = sets.Set(exclude)
excludeset
Set(['a', 't', 'w', 'n'])>>> for w in words:
... if not excludeset.intersection(w):
... print w
...
dog
fish
