2. The hardest section of code in the project to understand was: (explain what)

I think, you should add a lot more explanation to your code. E.g. in Q2 and Q4b where you have almost no explanation.

It is also not possible for me to run Q8. Maybe there is an error in the code? In this question, your code is also really long. You could improve it by inserting some of the code in the py file.

When I print your results in Q5b, I don't understand, how I should interpret the result.

Im not exactly sure if the printed lines in 5b are alle necessary. I also have a hard time going through the code in Q8 and pin-pointing the error code. As fpv111 mentions, maybe provide the code in the .py file so the code in the notebook is shorter?

question 4a and 4b can be written with more explanation. I cannot find the answer of question 4a. I think # So the price that maximizes utility is 1.887 with a corresponding utility of 0.634
this is the answer but it should show the result and you can add more information on it :)
