I'm new to Python.

I'm guessing you tried restarting, correct?

Did you use the official windows python installer from python.org? I'd recommend trying to reinstall with that installer.

Have you installed pyreadline?
If so pip uninstall pyreadline.
If not install with pip,just remove this file E:\Python312\Lib\site-packages\readline.py and try again.
readline.py is not part of Python default iinstall files,as it belong to pyreadline if look at file readline.py.
So dos it hook into low level stuff and can make this error.

Thanks you snippsat. I installed Python with the download Python.org/downloads. Removing the readline.py fixed the problem.

What did you install? 64-bit, ARM64, embeddable?
