How to make various list using random.sample()? [closed]

Question

in this list

AIB13seoul= ['김예나','김혜관','노주연','박진수','박희선','양건희','양세비',
             '이예지','전형준','정승기','sangwon','이지현','김강호','김슬기',
             '김용석','김재성','방준원','한유성','한현구','강병우']

I want to make 3 other random lists called a, b, and c without duplicates, using loop. I'm not used to utilizing loops, so this is how I tried originally:

import random
a = random.sample(AIB13seoul, 7)
list(a)
removed=list(set(AIB13seoul) - set(a))
b = random.sample(removed, 7)
removed1=list(set(removed) - set(b))
c = random.sample(removed1, 6)

And this is the file I'm using: off-site file

I tried this:

a=[]
for x in AIB13seoul:
    select=random.sample(AIB13seoul,7)
    a.append(select)

print(a)

but it didn't work .

You could write a fairly flexible implementation with numpy and random:

import random as rand 
import numpy as np


def split(list, subdivisions):

    l = rand.sample(list, len(list))
    splits = [int(len(l) * split) for split in np.linspace(0, 1, subdivisions + 1)]
    return [ l[splits[i] : splits[i+1]] for i in range(len(splits) - 1)]

split(AIB13seoul, 3)

Which results in:

> [['???', '???', '???', '???', '???', '???'],
  ['???', '???', '???', '???', '???', '???', '???'],
  ['???', '???', '???', '???', 'sangwon', '???', '???']]
