You asked for letters when you wanted to see the words. You actually build 
the list of words with

> [w for w in wordlist if len(w) >= 6
> and obligatory in w
> and nltk.FreqDist(w) <= puzzle_letters]

but don't even bind it to a name. Try

words = [
    w for w in wordlist if len(w) >= 6
    and obligatory in w
    and nltk.FreqDist(w) <= puzzle_letters
]
print words

to get what you want.
