我正在查看一些python 2.x代码，并尝试将其翻译为，py 3.x但是我仍然停留在本节中。任何人都可以澄清出什么问题吗？

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)

这是给出的错误：

TypeError: 'range' object does not support item assignment
