I believe you are either using an obsolete copy of the notebook file, or you have an obsolete copy of the w1_unittest.py file.

Both of these files were updated a few weeks ago.

Can I ask where you got your assignment files from?

it is the file that was launched by coursera

That’s odd, perhaps the notebook update process did not work on your account for some reason.

I think the problem can be fixed by updating your notebook and the unittest python file. Instructions are in the course FAQ here:
