    Make xrange py3 compatible

    In py3 ,
    Xrange is renamed to range,
    so it needs to be modified to make it compatible.
    the code:
    print (xrange(5))
    Traceback (most recent call last):
      File "code", line 4, in <module>
        print (xrange(5))
    NameError: name 'xrange' is not defined.
