Change arrow colour

I am trying to make a GUI program using tkinter and python3. When I try to create a submenu for a menu in the menubar, I get a 3D arrow unlike the arrow I usually get in other programs.
from tkinter import *
MainWindow = Tk()
MainWindow.title('MenuBar')
MainWindow.geometry(str(MainWindow.winfo_screenwidth()) + 'x' + str(MainWindow.winfo_screenheight()))
#Menu_Bar object
menubar = Menu(MainWindow, bd=0, activeborderwidth=0)
#File Menu Object
file_menu = Menu(menubar, tearoff = 0, bd=0, activeborderwidth=0)
file_menu.add_command(label =' New', command = None)
file_menu.add_separator()
file_menu.add_command(label =' Open', command = None)
#Create a sub-menu for Open-Recent
Open_Recent = Menu(file_menu, tearoff=0, bd=0,activeborderwidth=0)
Open_Recent.add_command(label = 'file1', command=None)
Open_Recent.add_command(label = 'file2', command=None)
Open_Recent.add_command(label = 'file3', command=None)
file_menu.add_cascade(label =' Open Recent', command = None, menu=Open_Recent)
file_menu.add_separator()
file_menu.add_command(label =' Save', command = None)
file_menu.add_command(label =' Save as', command = None)
file_menu.add_separator()
file_menu.add_command(label =' Import FIle as Module', command = None)
file_menu.add_separator()
file_menu.add_command(label =' Exit', command = MainWindow.destroy)
menubar.add_cascade(label ='Menu', menu = file_menu)
#Edit Menu Object
edit_menu = Menu(menubar, tearoff = 0, bd=0, activeborderwidth=0)
edit_menu.add_command(label =' Undo', command = None)
edit_menu.add_command(label =' Redo', command = None)
edit_menu.add_separator()
edit_menu.add_command(label =' UI', command = None)
edit_menu.add_command(label =' System', command = None)
edit_menu.add_separator()
edit_menu.add_command(label =' Rename', command = None)
edit_menu.add_command(label =' Batch Rename', command = None)
menubar.add_cascade(label ='Edit', menu = edit_menu)
#Assets Menu Object
Asset_menu = Menu(menubar, tearoff = 0, bd=0, activeborderwidth=0)
Asset_menu.add_command(label =' Set Folder', command = None)
Asset_menu.add_command(label =' Export as Asset', command = None)
Asset_menu.add_command(label =' Import Asset', command = None)
Asset_menu.add_command(label =' Browse Assets', command = None)
Asset_menu.add_command(label =' Set Icon', command = None)
Asset_menu.add_command(label =' Remove Icon', command = None)
menubar.add_cascade(label =' Assets', menu = Asset_menu)
#Adding Menubar to the window
MainWindow.config(menu=menubar)
mainloop()
Here is a screenshow from VSCode(the look I am going for)
Image1
And here is what I am getting
Image2

I just added bg = "black", fg = "white",activebackground="white" to each menu. I'm not sure if it's the right answer, but the result looks the exactly like image 1.
EDIT:
full code with the small changes.

How to display tab widget after a toolbar menu in Python?

I am new to this tkinter menu. I am trying to upload and display an excel file by using the 'filemenu' in the menubar and 'btnNew' in the toolbar menu.
The application did run but it does not display my excel file after I browse the file. The application only display the datatypes of each variable in the excel file.
import pandas as pd
import xlrd
import tkinter as tk
from tkinter import Frame, Menu, Button, Label, Canvas
from tkinter import LEFT, RIGHT, TOP, BOTTOM, X, FLAT, RAISED
from tkinter import filedialog
from tkinter import ttk
root = tk.Tk() #main method 1 - create main window (parent window)
root.title("Data Visualisation")
width = 1000
height = 500
screen_width = root.winfo_screenwidth()
screen_height = root.winfo_screenheight()
x = (screen_width / 2) - (width / 2)
y = (screen_height / 2) - (height / 2)
root.geometry('%dx%d+%d+%d' % (width, height, x, y))
root.resizable(1,1)
def browseFile():
global workbook, copyWorkbook, excel_file, sheetName, worksheet
fileName = filedialog.askopenfilename(initialdir = '/', title = 'New File', filetypes = (('excel file', '.xlsx'), ('excel file', '.xls'), ('all files', '*.*')))
excel_file = pd.ExcelFile(fileName)
workbook = xlrd.open_workbook(fileName)
sheetCount = workbook.nsheets
#Create tabs
sheetName = []
tab = []
for x in range(workbook.nsheets):
tab.append(ttk.Frame(tabControl))
sheetName = workbook.sheet_names()
tabControl.add(tab[x], text = sheetName[x])
df_table = excel_file.parse(sheetName[x])
print(df_table.dtypes)
lblTable = Label(tab[x], text = df_table.to_string(index = False)).grid()
btnGraph = Button(tab[x], text = "Graph").grid(sticky = 'w', column = 1, row = 5)
##MENU BAR
menubar = Menu(root)
root.config(menu = menubar)
#FILE MENU
filemenu = Menu(menubar, bg = '#BFBFBF', tearoff = 0)
menubar.add_cascade(label = 'File', menu = filemenu)
filemenu.add_command(label = 'New', compound = LEFT, command = browseFile)
filemenu.add_command(label = 'Open...', compound = LEFT)
filemenu.add_separator()
filemenu.add_command(label = 'Quit', compound = LEFT, command = root.quit)
#SEARCH MENU
searchmenu = Menu(menubar, bg = '#BFBFBF')
menubar.add_cascade(label = 'Search', menu = searchmenu)
searchmenu.add_command(label = 'Find...', compound = LEFT)
searchmenu.add_command(label = 'Replace...', compound = LEFT)
#HELP MENU
helpmenu = Menu(menubar, bg = '#BFBFBF')
menubar.add_cascade(label = 'Help', menu = helpmenu)
helpmenu.add_command(label = 'About', compound = LEFT)
##TOOLBAR MENU
toolbar = Frame(root, bd = 1, relief = RAISED)
#To browse excel file
btnNew = Button(toolbar, text = 'New', compound = TOP, relief = FLAT, activebackground = '#ADD8E6', padx = 20, pady = 2, command = browseFile).pack(side = LEFT)
btnOpen = Button(toolbar, text = 'Open', compound = TOP, relief = FLAT, activebackground = '#ADD8E6', padx = 10, pady = 2).pack(side = LEFT)
btnFind = Button(toolbar, text = 'Find', compound = TOP, relief = FLAT, activebackground = '#ADD8E6', padx = 10, pady = 2).pack(side = LEFT)
btnReplace = Button(toolbar, text = 'Replace', compound = TOP, relief = FLAT, activebackground = '#ADD8E6', padx = 10, pady = 2).pack(side = LEFT)
btnQuit = Button(toolbar, text = 'Quit', compound = TOP, relief = FLAT, activebackground = '#ADD8E6', padx = 10, pady = 2, command = root.quit).pack(side = RIGHT)
toolbar.pack(side = TOP, fill = X)
###Tab Widget
tabControl = ttk.Notebook(menubar)
tabHome = ttk.Frame(tabControl)
tabControl.add(tabHome, text = "Home")
#All the automation Tab is pack here
tabControl.pack(expand = 1, fill = 'both', side = LEFT)
root.mainloop() #main method 2 - run the application
The application should display tabs and in each tab, it should contain each sheet from the excel file. All the tabs must be display after the toolbar menu.
I'm not sure what is the problem as is does not specify if there is any error in my code.
All feedback is welcomed as I am trying to learn how to make a better interface using python. Thank you for your help :D

You set the wrong parent to the frame tabControl.
Change:
tabControl = ttk.Notebook(menubar)
to:
tabControl = ttk.Notebook(root)

I can't Manage to close from in Python 3 with tkinter

I am trying to build a xml parser in python, i start to build gui framework, and here i need to create some forms to save some settings values. I manage to make it work and save some values to txt files for startup. But what ever i tried i can't manage to close the settings form when i click button. i need to close it with the x on the window. i can't find the root of the issue.
what i am trying to do is, when i click Cancel, form will be closed. if i click Save, form will first save data then close.

How to display string variables in Tkinter?

I am trying to create a GUI program in python to generate random Lottery numbers. I want to have a menu bar for choosing Powerball or MegaMillion. And after choosing it, there will be buttons to let user select how many tickets to show. But I cannot make the method work. I want to show different lines of number lists when I click the button, but it does show anything. I'm not finished yet since it doesn't work. I am new to Python and programming, please help! Thank you !
from tkinter import *
import random
class lotteryNum:
def __init__(self):
window=Tk()
window.title("Lottery Number Generator")
menubar = Menu(window)
window.config(menu=menubar)
self.pbLst = [x for x in range(1,70)]
self.pbLst2=[x for x in range(1,27)]
self.mmLst = [x for x in range(1,76)]
self.mmLst2=[x for x in range(1,16)]
self.usingLst=["*"]*6
#Type Menu
typeMenu = Menu(menubar, tearoff = 0)
menubar.add_cascade(label = "Which Lottery", menu = typeMenu)
typeMenu.add_command(label="Powerball", command= self.powerBall)
typeMenu.add_command(label="Mega Milion", command= self.megaMillion)
#Exit menu
exitmenu = Menu(menubar, tearoff = 0)
menubar.add_cascade(label = "Exit", menu = exitmenu)
exitmenu.add_command(label = "Quit", command = window.quit)
#Welcome label
Label(window, text="Welcome to Lottery Generator!").pack()
frame=Frame(window)
frame.pack()
#Text Label
self.showResults = StringVar()
Label(frame, text=self.showResults).pack()
Button(window, text="$2", command=self.runLottery()).pack(side=LEFT)

random.shuffle(self.usingLst2)

I think your code should work if you change this line:
Label(frame, text=self.showResults).pack()
to this:
Label(frame, textvariable=self.showResults).pack()

Finished code just let whoever interested know what I'm try to do here.
