A Python server side implementation for jQuery Real Person Plugin

realperson.py

import numpy as np 
#------------------------------
def rpHash(person):
        hash = 5381

        value = person.upper()
        for caracter in value:
                hash = (( np.left_shift(hash, 5) + hash) + ord(caracter))
        hash = np.int32(hash)
        return hash
#-----------------------------

if rpHash(request.form['realPerson']) == request.form['realPersonHash']:
        print "Your are a real person!"
else:
        print "You are a bot!"

Thanks
