I don't think this will do what you think it will. It'll match
anything that has any one of the supplied letters (or a pipe; it's a
character class, so the pipe has no significance and is simply part of
the class). I'm not sure a regex is the best thing here; but what you
could do is sort the letters and sort the letters in the words:
pat = ".*".join(sorted(letters.lower()))
for word in open("/usr/share/dict/words"): # Ought to use with
if re.search(pat, ''.join(sorted(word))): print(word)
