what's the problem??????

[Avi Gross]

Nati,
This is a two-way process and requires you to be very clear on what is not working or what you are trying to do or help clear away having us try to understand lots of code that is not very related to the question.
Your code, as shown, makes an empty string repeatedly in a loop. 
a=dict()
I am guessing the code there works fine and does nothing useful. Well, what do you want in your dictionary? Most people create a dictionary outside the loop as an empty dictionary and then in the loop use one of many methods to add key:value pairs.
Earlier in the code you had another line:
a=labels.to_dict()

If the labels variable had a method like that, that is also a way.
So be specific about what LINE or region of code and what is wrong and what you already tried or error messages you got.
Avi
