How to fix "No module named 'w2_unittest'"

[Maryam_adz]

Hi,
I am new to Python. Can anyone help me fix this error in my lab assignment for week 2?

I think you might have changed something you are not supposed to from the Lab itself.

Its better to rest the whole lab now, follow the steps here:

Are you using Coursera Labs, or did you download the assignment to some other platform?

Hi @Maryam_adz

Please ensure that you’ve executed the first cell of the notebook to import the necessary libraries including w2_unittest. If the issue persists, try backing up your answers, restoring the initial version of the notebook from the checkpoints section, and then rewriting your code.

These are the first two code cells in the notebook.

Not much to go wrong in that.

I had initially downloaded the assignment, but I was able to resolve the issue by using Coursera Labs. Thanks for your help.
