I am trying to use a variable in a textbox instance name in order to shuffle through them in a for loop. For example, I have 14 text widgets(infoBox1 to InfoBox14) that I am trying to fill from a list. So what I am looking to do is the following:
for item in finalList:
x += 1
You don't need names to do such thing. You can put your widgets in a list then access those using indexes.
#you can create like this. Used -1 as index to access last added text widget text_list =  for idx in range(14): text_list.append(tkinter.Text(...)) text_list[-1].grid(...) #then you can easily select whichever you want just like accessing any item from a list text_list[x].insert(...) #or directly for idx, item in enumerate(finalList): text_list[idx].insert("end", item)
