input: Write a function to generate a list of numbers from 0 to 10 multiplied by 2. The function should return the list of these numbers.
  def multiply_by_2():
      return [i * 2 for i in range(11)]
  assert multiply_by_2() == [0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20]
output: def multiply_by_2():
      return [i * 2 for i in range(11)]
