argparse io issue

[snippsat]

So this part not only defines how the script would read a dictionary, but also how it will write to the console, correct?
Just to be clear.

No,the error happens before all the reading and use of argparse.
The problem happens in setup.py where read function is reading files like,
README.rst or __init__.py that contain metadata or other information needed in the setup script.
This can be hard to understand if you have not deal with building a package in Python.

If you want try as a excerice,here is step how it did rebuild this so it work in eg Python 3.12
