What is sqlite python error?

Error expected str, bytes or os.PathLike object, not tuple

Answer 1

img2 = open(f'{maxmark[2][0]}', 'rb')
            mime = magic.Magic(mime=True)
            filename = mime.from_file(maxmark[2])

Line one implies that the filename is maxmark[2][0]. Then maxmark[2] is probably a collection, tuple, list, or dictionary, because I don't think you're opening a file with a single character name. By the way, why f'{maxmark[2][0]}'?
But in line three, judging by the name of the method, you need to pass a string with the path to the file file - and maxmark[2] is passed there, which we have already defined as a possible tuple.
This matches the error text.
