Adding a new project to the Python curriculum

[jdwilkin4]

Hey @Dario-DC !

It looks like there already is a sudoku solver project in the quality assurance certification here https://www.freecodecamp.org/learn/quality-assurance/quality-assurance-projects/sudoku-solver

Are there concerns from the Python team about having duplicate projects so close together in two different certifications? Or will it be fine because one is in JS and the other will be in Python?

Thank you for pointing that out @jdwilkin4 . I really hope it will be fine to have them both. Originally this was not part of the new curriculum but we are a bit limited about what we can do in the platform as it is right now and we had to remove many projects. So removing this project would be quite problematic for us.
