Course 3 Week1 Exercise 8 and Exercise 10

In exercise 6, I don’t understand how to use Match None[None]: command.

In exercise 10, I am getting an error: ZeroDivisionError: float division by zero

Please let me know if you have some solutions. Additionally, zero grading error is also there.

You need to replace both “None” text with the name of a dictionary, and then a dictionary key.

You will get zero points until you complete the entire assignment and pass all of the built-in unit tests. You can’t grade an incomplete or incorrect notebook.
