Most of the objections from the previous try still stand: check your whitespaces (whitespace after every comma, whitespaces around operators, whitespace after "if" or "for" keywords), you have to be consistent. Comparing indices doesn't make much sense now that you don't check vertices, I think you should drop that too. You could probably instead check for min and max x, y and z vertices coordinates, verifying that the box has the expected dimensions.
