I'll take your word for it, as I don't use emacs. That makes sense,
though, as while researching this question I did find documentation
that suggests zsh disables ZLE under emacs.

OP, it sounds like in this circumstance, then, that you want
interactive Python without readline (which means a recompile, and from
a quick Google it sounds like it might not work). I'd leave readline
in the system Python and just tell emacs to use my custom one without
it, if I were you.

(Or save the trouble and just run ipy in a separate xterm :>)
