Creating an editing subsystem is a lot of work.  I created one that
knows the structure of the language, and it is distributed for free
with Python.  The only downside is that it uses a GUI, so it's not for
everyone.  Its name?  IDLE.

BTW, IDLE's rules are almost the same as those used by Emacs
python-mode.el.  Emacs *does* run in a classic TTY window.
