Bug report

Bug description:

When I use the Python REPL, I am used toPgUp browsing my prompt history based on the partial command I already typed.

Consider:

>>>import sys>>>import os>>>...>>> im[PgUp]

Python 3.12 REPL insertsimport os with my cursor betweenm andp. I can keep pressingPgUp to getimport sys and older commands from my history. I don't know if this is Fedora's configuration of readline, or the default. However, Bash and older Python REPLs behave that way, as well as IPython/Jupyter console.

Python 3.130b1 REPL changes my prompt toprint("a") when I pressPgUp. The particular command is my first line of~/.python_history. PressingPgUp again changes nothing.

CPython versions tested on:

3.13

Operating systems tested on:

Linux
