When I run the test for Exercise 2 it says that there’s an “Incorrect value for available_copies”, however below it says the grader expected 3 and that I got 3. The output is exactly as expected, but I keep failing the test.
Any ideas?
Perhaps the grader uses a different test.
It would help if you post a screen capture image of the error message or grader feedback.
Thanks for the image.
Note: That output is not from the ‘grader’, it’s from the in-notebook test cases.
Hopefully a mentor for that course will stop by shortly. Since it’s on Coursera and I’m not a mentor for that course, I don’t have access to do any investigation on the issue.
Ok got it, thanks so much!
Hi @dianexgutierrez,
I’m going to DM you regarding this.
Hi @dianexgutierrez,
I took a look a your notebook, and saw the mistake you are making.
In simple words, you were expected to do an arithmetic operation, something like:
x = y - z
But what you are doing instead is, doing the operation, but then turning it into a string.
x = f"{y -z}"
If you don’t understand what I’m about to say, don’t worry, you’ll learn about it as you progress through the course, but when you use quotes ("") with a variable, it then becomes of type str (string).
So the issue here is that “x” needs to remain an integer, but you have turned it into a string type.
If you take a look in your notebook, you can see what I mean. I left some comments for you in there.
Best,
Mubsi
ohh ok got, I can see it clearly now.
Thanks so much!
