How can I make the output with pair of list : content in my python code?

I have been developing a python web-crawler for this website(http://ift.tt/2i6fd3b). Until now, I made two functions, which works well separately. One is to collect the list of stock and another is to collect the content data of each list.

I would like to make the output of my code with pairs of "list#1/content#1", "list#2/content#2", "list#3/content#3", ... What code should I add at the last part of my code?

Please help me to work this out.

Thanks.
