How to disable duplicated items in random.choice

I want to grab a random items in a list using random.choices(), but I don’t need to grab some multiple items.
Example:

import random
mylist = ['python', 'c++', 'html', 'CSS', 'JavaScript']
print(random.choices(mylist, k=4)

in sometimes it returns this output:

['python', 'html', 'JavaScript', 'JavaScript']

So I want to remove the duplicated JavaScript, so it remains only one JavaScript and replace the duplicated one with a new item

['python', 'html', 'CSS', 'JavaScript']

>Solution :

Use this :

from random import sample
mylist = ['python', 'c++', 'html', 'CSS', 'JavaScript']
print(sample(mylist, k=4))
