Why do the tkinter windows open when the program runs and not when the buttons are pressed?

I am trying to code a journal using tkinter. I have used different scripts for each part of the journal (main menu, morning entry and evening entry). I have set it so that the windows for morning and evening entry only open when their respective buttons are pressed on the main menu and this works well but when I run the programs both windows open automatically without me pressing anything. This happens before the main menu window is even opened. I have checked through the code and not noticed anything that can be causing this. Below is my code for the main menu and for the morning menu (evening is the same as morning menu with variables changed).
Main Menu

hi guys, I am not sure why the nameCheck function is not being triggered.
I didn't put much effort into designing so it looks bad.
I used tkinter.
The start button in the titleFrame is supposed to trigger the nameCheck function that checks the playerName(in title frame entry) against pName(list).
Do I have to create a separate variable outside the function to store the playerName?
By the way, I am very new to coding, just found out what def is today. So please explain your code in detail, Thank you(^-^).

The button command extension is on a diffrent line as so
btnRead=tk.Button(root, height=1, width=10, text="Insert GUI",
command=getTextInput)

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 get the Scrollbar work during the multiple-entry (with condition) in tkinter frame within the tab?

I was trying to create the scrolled-abled in the frame, where there will be multiple entry lines according to the number of items present. My questions are
1.) My frame Nofy_frame1 with scrollbar is not working (Mentioned the comment #NOT WORKING part) and its position is too close to the entries I did not get any error response. How to solve it?
2.) How to stop/restart the loop while shifting the radio buttons of method 1 and method 2? Since for each click on Add entry button for method 2, the result would be :
Price 1 :
Price 2 :
Price 3 :
Price 4 :
Price 5 :
and then next click on the same Add entry button I am getting
Price 6 :
Price 7 :
Price 8 :
Price 9 :
Price 10 :
instead of the above result
How to resolve it?
I have written the fair code below, Please let me know and clarify my mistakes

How to block typing in Entry while still keeping its functionality?

I'm making a calculator using Tkinter. I want to be able to block the user from typing directly in the Entry, but still, i don't want to simply deactivate the Entry entirely, because i need my input commands from the buttons for it to work.
from Tkinter import *
root = Tk()
root.title("Calculadora")
root.resizable(height = False, width = False)
#functions------------------------------------------------------------------
display_input = StringVar()
number_storage = ""
def button_click(buttons):
global number_storage
number_storage = number_storage + str(buttons)
display_input.set(number_storage)
#row 1---------------------------------------------------------------------------
display = Entry(root, textvariable = display_input, justify = 'right', font = ("Simplified Arabian Fixed", 18), bg = "black", fg = "white", bd = 25).grid(columnspan = 4)
Button7 = Button(root, command = lambda: button_click(7), bd = 10, text= "7", padx = 9, font = ("Simplified Arabian Fixed", 15), bg = "black", fg = "white").grid(column = 0, row = 1, sticky = 'ew')

Pass state="readonly" when constructing the Entry; it still allows selecting the text, and changing display_input programmatically still changes the display, but it doesn't allow direct user input.
Per the docs:
state=
The entry state: NORMAL, DISABLED, or “readonly” (same as DISABLED, but contents can still be selected and copied). Default is NORMAL. Note that if you set this to DISABLED or “readonly”, calls to insert and delete are ignored. (state/State)
