Randomly Generate Letters in python

Question

I want to generate 10 unique English letters and append them to a list in Python.

This is what I tried:

for i in range(10):
    rand = random.choice(string.ascii_letters)
    print(rand)

Answer 1

This can be also the answer:

import random
import string

ls = []
while len(ls) !=10:
    rand = random.choice(string.ascii_letters)
    rand =rand.lower()
    if rand not in ls:
        ls.append(rand)

As this does get repeated alphabets. This code gets a random Unique 10 letters
