random list within a certain limit

i want to generate a random list, in which generates n numbers between a and b. However, when executing, nothing comes out.

def random_list(a,b,n):
    import random
    xs=[]
    x=random.randint(a,b)
    xs.append(x)
    while len(xs)==n:
        return xs

A small change in logic and small code move should fix it.

def random_list(a,b,n):
    import random
    xs=[]
    while len(xs)!=n:
        x=random.randint(a,b)
        xs.append(x)
        return xs

Also as others have mentioned, if you aware of list comprehension then please use them. That will make code much cleaner.

try this one (using randint with list comprehension to generate the random list)

import random

def random_list(a,b,n):
    xs = [random.randint(a,b) for _ in range(n)]
    return xs

output:

>>> print(random_list(1, 10, 4))
[6, 2, 6, 4]

>>> print(random_list(1, 10, 4))
[3, 9, 2, 1]

If you wish to keep the while loop, you could re-arrange your code to something like this:

import random

def random_list(a,b,n):
    xs=[]
    while len(xs) < n:
        x = random.randint(a,b)
        xs.append(x)
    return xs
