Why doesn't sorting work in python telegram bot?

Question

Python

This method should sort the elements of the list in random order, but for some reason this does not work in the bot. How to fix?

import telebot
import config
import random

from telebot import types

bot = telebot.TeleBot(config.TOKEN)

tasks = []

# random sorting of the array
def random_sorting():
  if len(tasks) > 2:
    for i in range(len(tasks) - 1, 2):
      rnd = random.randint(0, i-1)
      tasks[i], tasks[rnd] = tasks[rnd], tasks[i]

@bot.message_handler(content_types=['text'])
def prioritization(message):
  if message.chat.type == 'private':
    tasks.append(str(message.text))
    random_sorting()
    bot.send_message(message.chat.id, '\n'.join(tasks))

# run
if __name__ == '__main__':
  bot.polling(none_stop=True)

Answer 1

Wouldn't it be easier to use random.shuffle() ?
