Create multiple checkboxes from a list and get all values

Question

I would like to generate multiple checkboxes from a large list, and get all the values.

Here is my code so far (the list could be much larger):

from Tkin

Yes. You will need to store the data somewhere. I suggest making a dictionary.

from Tkinter import *

INGREDIENTS = ['cheese','ham','pickle','mustard','lettuce']

def print_ingredients(*args):
   values = [(ingredient, var.get()) for ingredient, var in data.items()]
   print values

data = {} # dictionary to store all the IntVars

top = Tk()

mb=  Menubutton ( top, text="Ingredients", relief=RAISED )
mb.menu  =  Menu ( mb, tearoff = 0 )
mb["menu"]  =  mb.menu

for ingredient in INGREDIENTS:
    var = IntVar()
    mb.menu.add_checkbutton(label=ingredient, variable=var)
    data[ingredient] = var # add IntVar to the dictionary

btn = Button(top, text="Print", command=print_ingredients)
btn.pack()

mb.pack()

top.mainloop()
