I'm sorry, I don't understand... why can't you?
py> text = "NOBODY expects the Spanish Inquisition!"
py> hash(text)
1245575277
There's also this:
py> hashlib.md5(text.encode('utf-8')).digest()
b'@\xfb[&\t]\x9c\xc0\xc5\xfcvH\xe8:\x1b]'
although it might be a bit expensive if you don't care about security and too
weak if you do. Can you explain why hash() isn't suitable?
For what's its worth, I wouldn't use sum() to generate a hash since it may be
unbounded and may not be "mixed up" enough. If you can't hash a string, perhaps
you can hash a tuple of ints?
py> hash(tuple(map(ord, text)))
-816773268
py> hash(tuple(map(ord, text+"\0")))
667761418
