Hey @ptrblck, Thanks for responding!  Yes, I create the tuples because the rest of my code uses it like that(it could also use lists so that can be changed). There is no Dataset code in the Tutorial ( I was indicating that I’m trying to take the tutorial further by using Datasets/Dataloaders)
My doubt is not around the fact that the tuple has become a list, it is more around why:
[‘A’,‘d’,‘a’,‘m’] become [(‘A’,), (‘d’,), (‘a’,), (‘m’,)]
Is this because of my tuple decision above ?
