how to access the output from clicking the recommendation button?

i am making a movie recommendation GUI with the help of a dataset. For that, i need the value selected from the list by clickng on the recommedation button but i am not able to figure out to do so.
from tkinter import *
import pandas as pd
window = Tk()
window.config(background = 'white')
window.geometry('700x500')
title = Label(text = 'Movie Recommendation', font = ('times new roman',20),background = 'white')
title.pack()
label = Label(text = '**********************', font = ('times new roman',17),background = 'white' )
label.pack()
label = Label(text = 'Movie List :', font = ('times new roman',17),background = 'white' )
label.place(x = 5, y =66)
scroll_bar = Scrollbar(window)
scroll_bar.pack(side = RIGHT, fill = Y)
list = Listbox(window, yscrollcommand = scroll_bar.set, height = 21, width = 40, background = 'white', foreground = 'black' )
for i in df['title']:
list.insert(END,i)
list.place(x=5,y=105)
rec = Label(text = 'Recommended Movies :', font = ('times new roman',17),background = 'white')
rec.place(x = 300, y = 66)
def selected_item():
print(list.get(ANCHOR))
# selected = Label(text = selected_item(),font = ('times new roman',15))
# selected.place(x=300,y = 96)
def movie():
button = Button(text = "Recommendation",foreground='black', command = selected_item,background = 'white')
button.place(x=5,y=460)
movie()
window.mainloop()
this is my code.
i tried everything i could think of but i am new to coding. thank you.

RE: TKinter Table Row Deletion (PYTHON)

(If anyone has seen my previous question, I found a way to save the row indexes and use them in the delete function :3)
Is there a way to stop/delete a running function/table on a button click? I am making a simple customer registration program which saves data from text fields (cID, custName, custEmail, and custBday) and deletes a selected row. My problem is that whenever I delete a row, the last row somehow leaves/lags behind creating this duplicate whenever a row is deleted. Any suggestions or is there something I've done wrong or I've missed?
My Code:
from tkinter import *
from tkinter import messagebox
import tkinter as tk
at = False
dotcom = False
list = [['ID', 'NAME', 'EMAIL', 'BIRTHDATE']]
recentIndex = []
ID = 1
storedIndex = 0

cEmail.set(list[event.widget._values][2])
birthdate.set(list[event.widget._values][3])
indexPosition = event.widget._values
recentIndex.append(indexPosition)
print(recentIndex)

You need to delete current displayed records before showing updated records inside createTable(). Also better create a frame for showing the records, so that it is more easier to clear the displayed records:
def createTable():
# clear current displayed records
for w in tableFrame.winfo_children():
w.destroy()
# populate records
for i in range(len(list)):
for j in range(len(list[0])):
mgrid = tk.Entry(tableFrame, width = 10, bg= 'yellow') # use tableFrame as parent
mgrid.insert(tk.END, list[i][j])
mgrid._values= i
mgrid.grid (row = i,column = j)
mgrid.bind("<Button-1>", callback)
...
# frame for showing records
tableFrame = Frame(window)
tableFrame.grid(row=5, column=5)

function to open a main GUI using a button from a PopUp GUI

I am new to Python, trying to make the Launch TFL App button open another GUI called "Menu GUI" but I don't know what to do for the def open_Menu(): function below. I want to use the popup GUI below as a launcher which takes the user to my main GUI. The only problem with the code below is that the button for launch TFL app doesn't do anything when you click it.
Here's my current code :
from tkinter import *
root = Tk()
root.title('TFL App')
p = Label(root, text = "TFL Journey Planner", height = "18", width = "250", bg = 'brown', fg =
'white',
font = ('Helvetica', '20', 'bold', 'italic'))
p.pack()
root.configure(bg = 'brown')
root.geometry('400x700')
photo = PhotoImage(file = 'trainstation.png')
label = Label(root, image = photo)
label.pack()
****#Buttons****
def open_Menu():
pass
Button1 = Button(root, text = "Launch TFL App", command = open_Menu, bg = "black", fg = 'white', padx
= 40,
pady = 10,
font = ('Calibri Light', '15', 'bold'))
Button1.pack(padx = 25, pady = 0)
Button2 = Button(root, text = "Exit ", command = root.destroy, bg = "black", fg = 'white', padx = 65,
pady = 8,
font = ('Calibri Light', '15', 'bold'))
Button2.pack(padx = 25, pady = 10)
root.mainloop()
How can I implement open_menu()
The code below is for my Main GUI which should open through the PopUp GUI above but the button on the PopUp GUI is not working.

Here is a solution using from subprocess import call. All you have to do is replace 'YOUR_FILE_NAME' with... your file name :D
from tkinter import *
from subprocess import call
root=Tk()
root.geometry('200x100')
frame = Frame(root)
frame.pack(pady=20,padx=20)
def open_Menu():
call(["python", "YOUR-FILE-NAME.py"])
btn=Button(frame,text='Open File',command=Open)
btn.pack()
root.mainloop()
What it will look like:
I hope this works for you :D

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)

Centering widgets in Tkinter frame using .pack()

I'm trying to get all of my labels and input boxes to be shifted down to the middle of the screen using the .pack() method. I tried using
anchor = CENTER
with the.place() method but that made everything overlap in the center. How can I simply shift all of my widgets to the center of my Tkinter frame?
Here's my code:
from Tkinter import *
root = Tk()
root.minsize(width = 500, height = 500)
root.wm_title("Email Program v1.0")
def callback():
print ("Hello!")
#sign in - email
usernameLabel = Label(root, text = "Email:")
usernameLabel.pack(padx = 0, pady = 0)
usernameInput = Entry(root)
usernameInput.pack()
usernameInput.focus_set()
passwordLabel = Label(root, text = "Password:")
passwordLabel.pack()
passwordInput = Entry(root, show = "*", width = 20)
passwordInput.pack()
passwordInput.focus_set()
#submit email credentials - connect to the server
submitEmail = Button(root, text = "Submit", fg = "black", width = 10, command = callback)
submitEmail.pack()
root.mainloop()

I managed to put those labels and entries to the center using three frames, two without any content just to 'eat' space.
frame1 = Frame(root)
frame1.pack(expand=True)
frame2 = Frame(root)
usernameLabel = Label(frame2, text = "Email:")
usernameLabel.pack(padx = 0, pady = 0)
usernameInput = Entry(frame2)
usernameInput.pack()
usernameInput.focus_set()
passwordLabel = Label(frame2, text = "Password:")
passwordLabel.pack()
passwordInput = Entry(frame2, show = "*", width = 20)
passwordInput.pack()
passwordInput.focus_set()
submitEmail = Button(frame2, text = "Submit", fg = "black", width = 10, command\
= callback)
submitEmail.pack()
frame2.pack(anchor=CENTER)
frame3 = Frame(root)
frame3.pack(expand=True)

The simple solution is to put all the widgets in a frame, and then center the frame.
