Get Random Element from List in Python

Introduction

In Python, you can easily get a random element from a list using the random module. This module provides a function called choice() which returns a random element from a given list. In this challenge, you will be asked to write a function that takes a list as an argument and returns a random element from that list.

Random Element in List

Write a function random_element(lst) that takes a list as an argument and returns a random element from that list.

Use random.choice() to get a random element from lst.

from random import choice

def sample(lst):
  return choice(lst)

sample([3, 7, 9, 11]) ## 9
