Display messages in window tkinter - python-3.x

Question

I am working on the following small tkinter application.
The URL & token is for a public development demo which can be found here if interested - https://snipe-it.readme.io/reference#api-overview
My current issue is displaying logging messages to the current tkinter window.
Currently it just prints to the console. I've tried a few different methods but I'm not very good with tkinter at the moment.
I have tried solutions like so - How do I create a popup window in tkinter? - but this just duplicates the main window each time.
Any help or pointers would be appreciated.
The csv file looks like so:
asset_tag,
1382613192,
1169063140,
785100692,
4565667567345457574535,

Here you go, this is assuming you want the messages as a popup. If not, create your own messaging window, or add a label or something you can update to the main one. I used the two messaging classes from the referenced post, but you can call them from anywhere and pass a message you want displayed.
import csv
import logging
from datetime import datetime
from multiprocessing import Process, Queue
from tkinter import *
from tkinter import filedialog, ttk
from tkinter.messagebox import showinfo
class App(ttk.Frame):
def __init__(self, master):
ttk.Frame.__init__(self, master)
self.label = ttk.Label(master, text="Bulk Checkin")
self.label.grid(row=0, column=0, columnspan=2)
ttk.Button(master, text="Select File",
command=self.select_file).grid(row=2, column=0)
ttk.Button(master, text="Checkin Assets",
command=self.checkin_assets).grid(row=2, column=1)
def select_file(self):
filename = filedialog.askopenfilename(initialdir="C:/Users/fraser/Desktop/", filetypes=(("CSV Files","*.csv"),))
self.infile = open(filename, "r")
print(self.infile.name)
def checkin_assets(self):
# function for Checkin Assets button click
# start a timer so we can see how long it takes
start_time = datetime.now()
output_q = Queue(maxsize=20)
procs = []
with open(self.infile.name, 'r') as myfile:
csv_reader = csv.DictReader(myfile)
line_count = 0
for row in csv_reader:
if line_count == 0:
", ".join(row)
line_count += 1
line_count += 1
asset_tag = row["asset_tag"]
my_proc = Process(target=get_asset_id, args=(
asset_tag, output_q, headers))
my_proc.start()
procs.append(my_proc)
# Make sure all processes have finished
for a_proc in procs:
a_proc.join()
# log how long this took
logging.info("\nElapsed time: " + str(datetime.now() - start_time))
def popup_bonus(self, message):
win = Toplevel()
win.wm_title("Message")
l = Label(win, text=message)
l.grid(row=0, column=0)
b = ttk.Button(win, text="Ok", command=win.destroy)
b.grid(row=1, column=0)
def popup_showinfo(self, message):
showinfo("Message", message)
def main():
main = Tk()
app = App(main)
main.mainloop()

I use easygui because it is the simplest and one-liner. It can work alongside tkinter so there is no compatibility issues. For example, if you want a messagebox/alert, just do this:
import easygui
easygui.msgbox('in cmd, type: "shutdown -a" within 20 seconds', title="Chance to abort shutdown")
