python - for loop to insert things into a tkinter window -

i have tkinter program has add significant amount of data window tried write loop take care of since have use string variable name of object tkinter running .insert() on object. didn't explain here method

def fillwindow(self):         global filedirectory         location = os.path.join(filedirectory, family + '.txt')         file = open(location, 'r')          ordersdict = {}         line in file:             (key, value) = line.split(':', 1)             ordersdict[key] = value          key in ordersdict:             ordersdict[key] = ordersdict[key][:-2]          item in ordersdict:             if item[0] == '#':                 if item[1] == 'o':                     name = 'ordered%s' %item[2:] 

right here problem line because have variable matches name of entry object created 'name' string variable gives me error "attributeerror: 'str' object has no attribute 'insert'"

                    name.insert(0,ordersdict[item]) 

here entire class. makes tkinter window , fills sort of shipping screen entries how many orders of thing needed. i'm new know things long way lot.

it looks have conceptual error there: inside method, variable "name" not exist last line on first listing. created, , points ordinary python string -- if using "name" variable elsewhere on class variable not exist inside method.

for easy fix of existing code, try calling variable "self.name" instead of name created, , on last line in method use: self.name.insert(0,ordersdict[item]) instead.

the self. prefix turn variable instance variable, shared across methods on same instance of class.

on side note, don' t need dictionary less 3 consecutive loops on method, insert relevant values extract "line" in text variable.
