I don’t know if I have something wrong in my settings or expectations, or if 
this is a bug.  Typing a tab in an Apple Terminal window while using any 
version of Python3 from MacPorts makes the terminal enter some kind of editing 
mode, instead of just indenting the line.  Python2 from MacPorts doesn't do 
this, and neither does Python3 from Apple, which makes me think that it's some 
kind of Python configuration issue in MacPorts.  The same thing happens when 
using iTerm2.

For example:

% python3
Python 3.8.15 (default, Oct 12 2022, 03:09:36)
[Clang 13.0.0 (clang-1300.0.29.3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>>/def f(): /<tab><tab> <--- anything typed here brings up old lines from

Do you see this with newer python versions? I don't see it in 3.10, FWIW. I remember there were some bugs with libedit support in older versions.

You can try installing py38-gnureadline, which will override the built-in readline module.
