python - Problems accessing Tkinter widgets in a list -

i'm trying write small program have list of labels , entry-fields using python , tkinter (see code below). adding widgets no problem. however, when want use method of 1 of instances (like insert() on 1 of entry-fields) can't figure out way it.

my code looks this:

from tkinter import * import random root = tk()  attributes = {'strength':10, 'dexterity':10, 'constitution':10, 'intelligence':10, 'wisdom':10, 'charisma':10} entries = [] labels = []  = 0 in attributes:    labels.append(label(root, text = a, justify = left).grid(sticky = w))    entries.append(entry(root).grid(column = 1, row = i))    = i+1  root.mainloop() 

and have tried simple

entries[i].insert("text insert") 

and

e = entry e = entries[i] e.insert... 

but hasn't helped. i've seen other examples of people trying use object in list, , seems doing did in first attempt. have missed something?

thanks

entry(root).grid() returns nonetype object, storing in list none. can create entry widget first, call grid() , append list.

from tkinter import * import random root = tk() attributes = {'strength':10, 'dexterity':10, 'constitution':10, 'intelligence':10, 'wisdom':10, 'charisma':10} entries = [] labels = []   i,a in enumerate(attributes):    labels.append(label(root, text = a, justify = left).grid(sticky = w))    e = entry(root)    e.grid(column=1, row=i)    entries.append(e)    entries[i].insert(insert,"text insert")    root.mainloop()
