I get a syntax error. The code won't even compile. I don't see how your code can avoid it. Are you sure your example works?
$ python3.8 Python 3.8.0 (default, Oct 28 2019, 16:14:01) [GCC 8.3.0] on linux Type "help", "copyright", "credits" or "license" for more information.
... time.sleep(1) File "<stdin>", line 2 time.sleep(1) ^ SyntaxError: invalid syntax
By the way, I noticed that python 3.9 implements pep 614, but I don't see how that could allow your example to work.
If I've made a stupid mistake, please be kind to me.
