Question about UNQ_C9 next_symbol function

I’m getting an error that one of the tests for the next_symbol function failed. I don’t know why. It looks like I’ve written the next_symbol function correctly. The rest of my assignment was graded correctly, but the next_symbol section was graded 0/10, which gave me a total of 90 points. If you have any idea why this is happening, or if you could take a look at my next_symbol function, please let me know.

CF) Information of length and shape are the parts that I added to the code to output.

You can chek in the File->Open the file where you can find the tests performed on this example at test_next_symbol(… function.

Try to understand the tests and then see why you are failing them.

Oh I see~
Thank you for letting me know that!
