Of course every major-mode implementation somewhere has this information
stored but there is no standard way of doing this.  Emacs builtin
support for parsing languages is pretty low level and focused on lisp
(read about syntax tables in the manual).

All major modes come with additions to this low level parser (mostly a
bunch of regexps and good guess work, no real parser).  If python is
your only concern read the source.
