Clarification in MLS- C1- Week 3 -programming assignment

Course Q&A Machine Learning Specialization Supervised ML: Regression and Classification
1

I need help from a mentor. The following are my problems.
I submitted a programming assignment for evaluation.
Exercises 1 and 2 (sigmoid and cost function) were complete and answers were correct.
Other exercises were not attempted.
Questions

  1. I received 0/100 marks. I thought some marks will be given for correct solutions.
  2. I got the following error message
    Cell #14. Can’t compile the student’s code. Error: TypeError(“unsupported operand type(s) for +=: ‘NoneType’ and ‘NoneType’”)
  • Question: What is the likely error in the coding?
  1. I think that there is a mismatch in function definition (Cell no 13) and function call (Cell no 14) in the assignment
    Thank you very much.

Dear Mentor (Shanup)
Thank you very much for your help and resolving the error message.
I am sharing the code problem below:
Error came from a part which was not attempted by me. (undefined ‘Null’)
Regarding grade: My observation is system gives grades at the end of complete submission).
Thanks for this help from the mentor, I could complete the assignment and pass the course. At the end system response was that each if the exercise was done correctly).

Congratulations @dinesha on succesfully completing Course 1. With the confidence that you have gained from Course 1, you can now step into Course 2, where you will encounter the very “cool :sunglasses:” Neural Networks, among other amazing algorithms.
