I am having some understandable behaviour from one of my function name week_graph_data() which call two functions those return a big tuple of tuples, But in function week_graph_data() line no. 30 does not work(returns no result in graph or error).
I have check both functions are called in week_graph_data() individually and those run perfectly. (returning tuple of tuples) here is my code: pastebin.com/ck1uNu0U -- https://mail.python.org/mailman/listinfo/python-list
