Why is there no xrange function in Python3?

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

Simple example:

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()

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:

1.53888392448
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.

I was preparing for my coding interview, thanks for clarifying this - Why is there no xrange function in Python3? in Python is not the simplest one. I am just not quite sure it is the best method

Maybe there are another answers? What Why is there no xrange function in Python3? exactly means?. Checked yesterday, it works!

imp Python module is always a bit confusing 😭 Why is there no xrange function in Python3? is not the only problem I encountered. Will get back tomorrow with feedback
