Use new REPL for the "code" module

Feature or enhancement

Proposal:

When installing Django in a Python 3.13 virtual environment and using Django's shell command, the old REPL is used.

It would be great if the code module supported the new REPL. From @ambv's reply in https://github.com/python/cpython/issues/119433#issuecomment-2130060062 it looks like this will be considered in Python 3.14.

I would also like to know what projects should do in the meantime. For example, I found a way to modify Django's shell command in one's own project to use the new REPL, by using this within a try-except block:

from _pyrepl.simple_interact import run_multiline_interactive_console
run_multiline_interactive_console()

Is this an acceptable workaround before Python 3.14 is released? Or should this function not be relied on, seeing as it's in an undocumented module?

Has this already been discussed elsewhere?

首先审查 Python 代码模块和所引用的 _pyrepl.simple_interact workaround，然后阅读链接的 CPython 讨论和 PR gh-148261。完成标准是确定代码模块应如何使用新的 REPL，并明确该 workaround 在 Python 3.14 之前是否适用。
