TypeError: 'range' object does not support item assignment

I was looking at some python 2.x code and attempted to translate it to py 3.x but I'm stuck on this section. Could anyone clarify what is wrong? 

import random

emails = {
    "x": "[REDACTED]@hotmail.com",
    "x2": "[REDACTED]@hotmail.com",
    "x3": "[REDACTED]@hotmail.com"
}

people = emails.keys()

#generate a number for everyone
allocations = range(len(people))
random.shuffle(allocations)

This was the error given:

TypeError: 'range' object does not support item assignment

if you can use numpy library you can replace range with np.arange:

import numpy as np
allocations = np.arange(len(people))

In Python 3, range returns a lazy sequence object - it does not return a list. There is no way to rearrange elements in a range object, so it cannot be shuffled.

Convert it to a list before shuffling.

allocations = list(range(len(people)))
