Depending upon your constraints, another way to approach this problem may be
better.  If you can get your word (or Word) dictionary, then you can build a
compiled form that collapses your search.  The compiled form of a word takes
the letters of a word and sorts them.   Use the compiled form as a
dictionary key to the original word (or words).  For example:
'bar' and 'bra' both compile to 'abr'.  Thus

words = {'arb': ('bar', bra')}

When you want to check a word, compile it by sorting its letters and test
its key against your words dictionary.

    compiled_word = string.join(a, '')
    if words.has_key(compiled_word):
        print words[compiled_word]

This would be blazingly fast, but would depend upon compiling your word
list.  There are lots of pretty complete text lists of English words
available on the web.
