how in python to generate a random list of fixed length of values from given range?

Question

How to generate a random (but unique and sorted) list of a fixed given length out of numbers of a given range in python?

Something like that:

>>>> list_length = 4
>>>> values_range = [1,30]
>>>> random_list(list_length,values_range)

[1,6,17,29]

>>>> random_list(list_length,values_range)

[5,6,22,24]

>>>> random_list(3,[0,11])

[0,7,10]

Answer 1

A combination of random.randrange and list comprehension would work.

import random
[random.randrange(1, 10) for count in range(0, 4)]

Answer 2

>>> import random
>>> random.sample(range(30), 4)
[3, 1, 21, 19]
