How to set up automatic syntax check for Python 3 in Emacs?

Question

Python

Found a lot of advice on the net. So far nothing has been set up. Everything works with Python 2. Apparently, hands do not grow from there, from where normal people have. Maybe someone here can help? Interested in Python 3.
