input: Write a python function to filter numbers divisible by 5 from a list.
  assert filter_divisible_by_5([5, 10, 15, 20, 25, 30]) == [5, 10, 15, 20, 25, 30]
  assert filter_divisible_by_5([3, 7, 11, 20, 25]) == [20, 25]
  assert filter_divisible_by_5([2, 4, 6, 8]) == []
output: def filter_divisible_by_5(numbers):
      return [num for num in numbers if num % 5 == 0]
