Proposal: Improve input validation in a Python example #3233

Hi! I'm interested in contributing to this repository.

I've been exploring the Python examples and would like to help improve the reliability of one of the scripts.

I'm planning to identify an example that could benefit from better input validation or error handling, and propose a small, focused improvement.

Before making changes, I'd like to ask whether this type of contribution would be welcome, as suggested in the CONTRIBUTING guidelines.

Thanks for your time!
