C-M-a means “hold control and meta at the same time and then press a”.

C-h k (hold control, press h, let go of h and control, press k) followed by key presses will tell you what emacs saw and what function it will run.

Probably don’t want to do that for python, instead do https://github.com/wyuenho/emacs-pet

Have you read the whole tutorial?

C-h k then scroll and see what emacs thinks is happening.

emacs is not going to be a good fit for that style of work, unfortunately

why don’t you just try it and see if you personally like it for your personal tasks and requirements

of course not
