  assert filter_long_strings(['Python', 'is', 'Fun']) == ['Python']
  assert filter_long_strings(['Longer', 'Than', 'Five', 'Char']) == ['Longer', 'Than', 'Five', 'Char']
  assert filter_long_strings(['Short', 'Tiny']) == []
  assert filter_long_strings([]) == []
output: def filter_long_strings(strings):
      return [s for s in strings if len(s) > 5]
