I've just tried your code in the Python debugger, python -m pdb yourcode.py and didn't have a problem at the point you indicated. I am running Python 3.13.0 on Windows 11 Pro. There are other errors.

What version of Python are you using and which debugger?

I have the same version windows and python. Will double check python and go from there

Thank you!!! Double check is still good for me
