How to obtain the same random sample from a list in Python

I have a small script to get a random sample from a list, however I want to always get the same list whenever I run this script. How should I do this?

My code currently is as follows, however each time that I run the script, I get a different sample.

import random

def SampleWithoutRepetition(population, sampleSize):
    random.seed(100)
    result =  random.sample(set(
        map(lambda attribute: attribute, population)), sampleSize)
    print(f"result: {result}")
population = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k']

SampleWithoutRepetition(population, 4)
