input: Write a python function to separate even and odd numbers from a list.
  assert separate_numbers([2, 3, 5, 6, 8, 9, 10]) == ([2, 6, 8, 10], [3, 5, 9])
  assert separate_numbers([1, 4, 7, 10, 13, 16]) == ([4, 10, 16], [1, 7, 13])
  assert separate_numbers([11, 22, 33, 44, 55]) == ([22, 44], [11, 33, 55])
output: def separate_numbers(lst):
      evens = [num for num in lst if num % 2 == 0]
      odds = [num for num in lst if num % 2 != 0]
      return (evens, odds)
