i have a have listbox that is bind to itemlistcallback function. i want to create label by clicking on a item in listbox for first time and update it if it was clicked more than once. the result is no matter on what item i click on, only the last label change.

its a receipt system for a restaurant that is going to increase quantity of item by clicking on them.

def itemlistcallback(event):
       selection = event.widget.curselection()
       if selection:
           global rowcount
           global itemqty
           global itemid
           global itemcount
           print(rowcount)
           rowcount +=1
           index = selection[0]
           data = event.widget.get(index)
           orderitemslist.insert(0,data)

           if data[0] not in itemset:
              itemid = "itemnamelbl"+str(data[0])
              itemcount = "itemcount"+str(data[0])
              itemid = Label(orderitemframe, text= data[1], font= ('Helvetica 12 bold'))
              itemcount = Label(orderitemframe, text=itemqty, font= ('Helvetica 12 bold'))
              itemid.grid(row=rowcount, column=1, padx = 0, pady = 0,sticky='n')
              itemcount.grid(row=rowcount, column=0, padx = 0, pady = 0,sticky='n')
              itemset.append(data[0])

           else:         
              itemqtyy = itemcount.cget("text")
              itemcount.config(text = itemqtyy+1)
           

       else:
          pass
   itemslist.bind("<<ListboxSelect>>", itemlistcallback)

i’d tried winfo_exists() to check if a widget exist or not, after getting no result, i make a list of what ids added to create a widget.
