input: Write a python function to filter numbers in a list that are divisible by a given divisor.
  assert filter_list([1, 2, 3, 4, 5, 6], 2) == [2, 4, 6]
  assert filter_list([10, 20, 33, 46, 55, 60], 5) == [10, 20, 55, 60]
  assert filter_list([12, 15, 22, 30, 42, 50], 3) == [12, 15, 30, 42]
output: def filter_list(lst, divisor):
      return [num for num in lst if num % divisor == 0]
