[Python] Python - tkinter button freeze

I have problem with freezing application in Python. I used tkinter library to make some app. When I using Send button it calls the functions that lasts 3 minutes and freezing application on this 3 minutes... I want to see all logs from this function "live". I can't wait 3 minutes and then get all the logs.

Below is example of my code:

import tkinter as tk
from tkinter import ttk
from tkinter import scrolledtext
import time


class Frames:

def main_frame(self, win):

# Main Frame
main = ttk.LabelFrame(win, text="")
main.grid(column=0, row=0, sticky="WENS", padx=10, pady=10)
return main

def button_frame(self, win):

# Button Frame
butt_frame = ttk.LabelFrame(win, text="Button")
butt_frame.grid(column=0, row=0, sticky='NWS')

def _send_button():
for i in range(10):
self.write_text_console("{0}\n".format(i))
time.sleep(0.5)

# Send Button
ttk.Label(butt_frame, text=" ").grid(column=0, row=8)
button = tk.Button(butt_frame, text="Send", command=_send_button, foreground='black')
button.grid(column=0, row=13, sticky=tk.EW)

def scrolled_text_widget(self, win):
ttk.Label(win, text=" ").grid(column=0, row=1)
ttk.Label(win, text="Console Output:").grid(column=0, row=2, sticky=tk.W)
self.scr = scrolledtext.ScrolledText(win, width=100, height=10, wrap=tk.WORD, state="disabled")
self.scr.grid(column=0, row=3, columnspan=5)

def write_text_console(self, string, color="black", tag="console"):
self.scr.configure(state='normal')
self.scr.insert('end', string, tag)
self.scr.tag_config(tag, foreground=color)
self.scr.configure(state='disabled')
self.scr.see("end")


win = tk.Tk()
win.geometry("845x300")
win.resizable(0, 0)
frames = Frames()
main = frames.main_frame(win)
frames.button_frame(main)
frames.scrolled_text_widget(main)
win.mainloop()


This example showing my problem. When you click the Send button it freeze app for 5s. But I need to see the logs during the loop.

How can I resolve it?
