If you remove the ability to write ioctls to tty stdio, for example on macOS by doing
sandbox-exec -p '(version 1) (import "system.sb") (allow process-exec) (allow file-read* (subpath "/"))' python3.13Then PyREPL fails:

You can work around this, by re-enabling ioctls:
sandbox-exec -p '(version 1) (import "system.sb") (allow process-exec) (allow file-read* (subpath "/")) (allow file-ioctl (regex "^/dev/ttys[0-9]*"))' python3.13but pyrepl should probably be robust to this and fall back to a regular console.
