It seems what you are trying to do is actually a functionality
of electric-layout-mode,  right? It's creating newlines between
two sets of '"""' so that if the user types one newline between
them, then one extra newline is inserted after and the line is
indented one level deeper than the '"""'.

If so, it would seem like 'electric-layout-rules' would be a good
match.  The behaviour would happen _only_ if the user has
electric-layout-mode, which is the standard Emacs mode for
controlling this kind of electricity.  The last paragraph
of the docstring of 'electric-layout-rules' seems to describe
a powerful enough mechanism to do achieve what the custom
psif does.
