Python: Live update of lists and dictionaries?

Python 3.6

Hello all, I can't seem to figure out how to get my GUI interface to live update a label. This label contains information from a list and this list is manipulated via buttons. However the number does not update! I've have tried using after() but after many failed attempts I don't understand how to get it to work.

Would I need to put it into a function that would then update my GUI? Or how else could I achieve this? I am still learning to program and very new to it. Any other tips are greatly appreciated! Thank you!

My label:

stock5 = Label(Stockframe, font=('Agency FB',20), text=(stock['Intel i7-
7770T QUAN'][0]))
stock5.grid(row=0, column=5)

My list:

{'Intel i7-7770T QUAN' : [3] }

I have tried this but to no success:

def updater():

     after(1000, updater)

     updater()

I am most probably misunderstanding how to use after()! Thank you!

Your updater function needs to actually update the label.

Assuming that stock5 and stock are global variables, and assuming that you are somehow updating stock on a regular basis, something like this would work:

def updater():
    new_value = stock['Intel i7-7770T QUAN'][0]
    stock5.configure(text=new_value)
    after(1000, updater)
