input: Write a python function to filter numbers greater than a given value.
  assert filter_numbers([1, 2, 3, 4, 5, 6, 7, 8, 9, 10], 'greater than') == [6, 7, 8, 9, 10]
  assert filter_numbers([10, 15, 3, 7, 8, 9, 20], 'greater than') == [10, 15, 7, 8, 9, 20]
  assert filter_numbers([5, 3, 2, 1, 0], 'greater than') == []
output: def filter_numbers(numbers, condition, value=5):
      if condition == 'greater than':
          return [number for number in numbers if number > value]
