[Tkinter] apply command on every list element

[flash77]

Hello,
thanks a lot for your answer!!

Do you mean it this way?

import tkinter as tk
from tkinter import Entry, IntVar, Tk
fenster = tk.Tk()

fenster.geometry("500x540")
fenster.resizable(width=0, height=0)
l=tk.Label(fenster, text="Sudoku Solver")
l["font"]="Arial"
l.place(x=240,y=0)

Square = []
def SquareCreate(): 
    for i in range(0, 9):
        for j in range(0,9):
            data = IntVar()
            t = tk.Entry(fenster, textvariable=data, font=("Times New Roman",12))
            t.place(x=i*40+70, y=j*40+80, width=40, height=40)
            Square.append(data)

def quit():
    fenster.destroy()
            
#Hauptprogramm
SquareCreate()
b=tk.Button(fenster, text="schließen", command = quit)
b.place(x=50,y=450)
print(Square)
fenster.mainloop()

But I'm not sure how to place the get() in SquareCreate().

Thanks for your patience!
