undefined example in lesson

Question

Within a lesson (Machine Learning course) instead of showing the results of a calculation, as the text indicates that it would show, I see a black text box where the result should appear, and in white text the word “undefined”. This occurs frequently through the course (I’m halfway through). So I don’t get to see the results Sololearn indicates that it is about to show me. This makes it difficult to follow the logic of the lesson. Does anyone know why this situation exists?

Answer 1

This happened to me as well (In the Python For Beginners course). I figured it out using my experience from block-based coding and other programming languages. So, try and figure it out from other Python courses. You finished the main Python courses!

Hope this helps
