This is a follow up to:

• https://bugs.python.org/issue46348
• bpo-46348: modernize test_typing #30547

There are several other cases I've missed:

1. There's a test that is only executed under `<3.6`. I think that it should be removed:

   cpython/Lib/test/test_typing.py

   Lines 4093 to 4099 in 0bbf30e

   	def test_namedtuple_pyversion(self):
   	if sys.version_info[:2] < (3, 6):
   	with self.assertRaises(TypeError):
   	NamedTuple('Name', one=int, other=str)
   	with self.assertRaises(TypeError):
   	class NotYet(NamedTuple):
   	whatever = 0

2. Line `if sys.version_info[:2] > (3, 2):`

   cpython/Lib/test/test_typing.py

   Line 1943 in 0bbf30e

   if sys.version_info[:2] > (3, 2):

3. Line `if sys.version_info >= (3, 3):`

   cpython/Lib/test/test_typing.py

   Line 2069 in 0bbf30e

   if sys.version_info >= (3, 3):

I hope that this is it!

PR is on it way :)
