The errors appear because it's your task to implement the functions so that the tests (who output the errors you're seeing) 'pass'.
As we can see in the code, the __ne__ function is simply not implemented yet and a NotImplementedError error is raised. You are meant to remove this line and implement the function's functionality. That's the whole task here.

FYI, chapter 1 of the book also state you need to open ecc.py to start the exercise. I can see this confuse some people though, since i expected explicit instruction such as "To solve exercise 1, you need to open ecc.py and edit __ne__ function".

You can see this in action in the code that accompanies this book. Once you’ve set up Jupyter Notebook (see [setting_up]), you can navigate to code-ch01/Chapter1.ipynb and run the code to see the results. For the next exercise, you’ll want to open up ecc.py by clicking the link in the Exercise 1 box. If you get stuck, please remember that the answers to every exercise are in [appendix_solutions].

Spoiler: Here, in the answers.py file, you can see the solution to the exercise 1:

As I suspected, you're meant to simply implement the __ne__ function. So no, there are no systematic errors, it's the whole repo's purpose to give you programming problems to solve, which then result in working tests (and no error messages).

I can confirm copying the answer to ecc.py (rather than trying add function to imported object) works (passed the test).

Yeah, I've been aware of ecc.py and answers.py . The functions were implemented into ecc.py from the beginning

To be safe I copied and pasted functions from answers.py into ecc.py . The problem still persists

Importing answers.py itself into doesn't do anything

Copying and pasting the functions themselves in the program does not help as well
