New in ML and need some help

Hello everyone, I am a beginner in the ML course. I am comfortable with mathematical formulas, however I am having difficulty with the evaluation of modules 2 and 3. Would someone be available to help me understand how to write the code? I also accidentally modified some lines of code provided at the beginning and I can no longer make them reappear. Your help would be welcome.

Which course are you attending? Please be specific.

As Tom says, it would be helpful to know which course you are taking.

If you want to get a fresh unmodified copy of an assignment, here is a thread that shows how to do that, which works for all the courses that use Jupyter notebooks on Coursera. I have not taken any of the short courses, but my guess would be that the thread I gave is not relevant for those course assignments.

Have you attended a Python programming course? You would only need to understand the essentials (defining and using functions, scope of variables, and program flow structures).

I don’t really have a basic knowledge of Python. But I started following tutorials on YouTube.

That’s a good way to get started. Hopefully the videos allow you to duplicate what they’re demonstrating, that’s a very good way to learn.

Thank you so much!
