Whenever i am trying to submit the assignment it shows error like this. I have written the code with the help of an LLM because i have no knowledge about python so please anyone help to submit the program and pass this assignment.

Try refreshing your workspace and submitting again.

Hello, my friend as i see in the screenshoot the test’s not passed, pleas for more information and to see the error msg, make give as the error’s msg after you excute the test for each exercice.

It looks like you’re running into a version mismatch with the assignment.

First, go to the “?” icon in the top right corner and select “Get Latest Version”. Before doing that, make sure to rename your current notebook so you don’t lose your work.

Also, from your screenshot it seems you’re importing libraries inside the solution cell, which the instructions usually don’t allow.

So the steps should be:

  1. Rename your current notebook
  2. Pull the latest version of the assignment
  3. Re-try the exercise following the instructions carefully (including not adding extra imports)

That should fix the issue.

i have already done the above instructions and i do not know python language properly. so i wrote the code with the help of LLM entirely. I have also try Rename your current notebook

  1. Pull the latest version of the assignment

  2. Pull the latest version of the assignment

What error are you getting now? Did you update the version of the notebook…

This is the error i am getting now. i have followed your instructions properly and done it again as you can see in the screenshot

Did you try this and get a new notebook? Remember that you need to either delete or rename your current notebook; otherwise, it won’t update because both have the same name.

If you tried this and successfully got the new notebook, then the issue is likely resolved. However, if you are still seeing the error saying that you don’t have the latest version of the assignment, it means the update has not been applied yet.

Please try again after deleting or renaming your current notebook and make sure you open the newly generated version.

Let me know what you observe after doing this, because if the problem persists even after that, we’ll need to investigate further.

in the sixth screenshot i am updating the python notebook site after deleting all the notebook

in the seventh screenshot the site is updating

in the eighth screenshot after updating the site all the previous notebook returns. i don’t know why but after updating the site doesn’t update.

First, posting your own solution code in the forum—whether it is correct or incorrect—is not allowed under the code of conduct. The forum is designed for discussion, hints, and learning support, not for sharing full attempted solutions.

Additionally, if you delete the current notebook and create a new one with the latest version, the new notebook will appear with the same official name as the assignment, but it will be without solutions between start and end comments. You will need to fill it in again from scratch, as it does not carry over your previous work.

Once you delete your current version and submit an updated solution, what are you getting as feedback from the grader?
