Why is there no xrange function in Python3?

by

Recently I started using Python3 and it’s lack of xrange hurts.

Simple example:

  1. Python2:

    from time import time as t
def count():
  st = t()
  [x for x in xrange(10000000) if x%4 == 0]
  et = t()
  print et-st
count()

  2. Python3:

    from time import time as t

def xrange(x):

    return iter(range(x))

def count():
    st = t()
    [x for x in xrange(10000000) if x%4 == 0]
    et = t()
    print (et-st)
count()

The results are, respectively:

  1. 1.53888392448
  2. 3.215819835662842

Why is that? I mean, why xrange has been removed? It’s such a great tool to learn. For the beginners, just like myself, like we all were at some point. Why remove it? Can somebody point me to the proper PEP, I can’t find it.
