ctrl + c on latest PDM exits python interactive session instead of clearing the current line

• I have searched the issue tracker and believe that this is not a duplicate.

Make sure you run commands with -v flag before pasting the output.

Steps to reproduce

Before, when I ran pdm run python I was able to use ctrl + c to clear the input in the current line of the terminal. Now it exits the terminal completely which is not what happened before.

Actual behavior

In a direct call of python3 ctrl + c does not quit the interactive session.

❯ python3                   
Python 3.10.6 (main, Oct  3 2022, 19:34:55) [Clang 13.1.6 (clang-1316.0.21.2.5)] on darwin

>>> 
KeyboardInterrupt
>>> 

In an instance of pdm run python3 or pdm run, a ctrl + c exits the session.

definitely something fishy going on here...this was not the case before the latest PDM. I am also using a pyenv shell of 3.10.6 so it is weird to me why the 3.11 is showing up

[pawamoy]

Confirmed on my end as well.

This is caused by a fix for a weird issue of uvicorn: #1474 (comment)
The exact commit is 0edac2e

Nothing wrong, it is because PDM is installed with Python 3.11, it is different from what you use for your current shell or project.

I am still facing this issue on PDM version 2.12.3.
