input: Write a python function to shuffle a list of numbers using the shuffle function from the random module.
  assert shuffle([1, 2, 3, 4, 5]) != [1, 2, 3, 4, 5]
  assert len(shuffle([10, 20, 30, 40, 50])) == 5
  assert set(shuffle([7, 8, 9])) == {7, 8, 9}
output: import random
  
  def shuffle(numbers):
      random.shuffle(numbers)
      return numbers
