In your code that line is not executed. And if it was at some stage, it will give you an error. max_item is a list and you cannot put a string and a list together: "TypeError: cannot concatenate 'str' and 'list' objects".
What are trying to do with this line? 'maximum = 0' and so product will be greater than maximum. It looks you are trying to append a list to seq that is already there? Maybe it's a bad guess from me, I'm no expert.
