# Intro to Programming and Data Science (Fall 2022)/Week 2 Coding Challenges

As a reminder, it's not essential that you solve or get through all of these — I'm not grading your answers on these. That said, being able to work through at least many of them is a good sign that you have mastered the concepts for the week. It is always fine to collaborate or work together on these problem sets but I encourage you to make sure that you understand the concepts yourself.
