os.walk() function giving stop iteration error

Question

import tkinter as tk

from tkinter import *
import os

master = tk.Tk()
listbox=Listbox(master,selectmode=MULTIPLE,width=20,height=10,font=("Calibri", 12),exportselection=0)
listbox.pack(side=LEFT,fill="y")

tk.Label(master, text="Enter Folder Path ").pack(fill=tk.X,padx=120)

e1 = tk.Entry(master,width=120)
e1.pack(fill=tk.X)

path=e1.get()
folders=sorted(next(os.walk(self.path))[1],key=int)
listbox.insert(END,*self.folders)

I am trying to load listbox with the subfolder names in a directory. While running this code following error pops up:

folders=sorted(next(os.walk(self.path))[1],key=int)
StopIteration

Can someone let me know what can be done in this case? I know this issue is coming up because of os.walk function.

One reason this happens because the folder you're trying to walk through doesn't exist.

Try checking if the value in self.path does indeed ponit to a directory that is reachable.

Yes The path is reachable – SaEIHN Sep 20 '19 at 14:59
@SaEIHN Add `print(os.path.exists(self.path))` directly above the `os.walk` line. – 9769953 Sep 20 '19 at 15:05
