It’s not really much extra effort though

They just added so e text to the __repr__ method on the exit callable object

That’s much easier than figuring out if your running this interactively and trying to figure out if this is going to break stuff.

Lemme golf that

~ $ python
Python 3.12.10 (main, Apr  9 2025, 18:13:11) [Clang 18.0.3 (https://android.googlesource.com/toolchain/llvm-project d8003a456 on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> class x:
...  def __repr__(s):
...   exit(0)
...
>>> xit = x()
>>> xit
~ $

Not that hard

repr is generally assumed to be side effect free and cheap to run, so things like debuggers tend to show repr of things in scope, including possibly exit

also then it behaves differently between repl and script, since repr never gets run. to do it properly it has to be a new repl keyword I imagine, but I still don't know if I'm sold on the idea

Good points. You're right, it does need solved at the shell level. Glad they did so.

The code isn’t high effort, it’s all the stuff you have to think about breaking

But generally I don’t think anyone prints exit in most contexts

Ps mad respect for doing that on your phone
