[Tkinter] Tkinter problem
#1
1.if you just run this, youll have a window to input 'order' and 'Rs'.
2.Enter a number in 'order' and press ok.
3.Change the number in 'order' again and press ok again.
youll know what wrong's with it.

QUESTIONS:

First: how can i cover these elements created by clicking 'ok'?
Second: is there any way that i dont have to have a button but show the elements right after i enter a number in 'order'

Thank you!!!!

import tkinter as tk
R=[]
C=[]
order=0

def GUI():
    window=tk.Tk()
    window.title('variable assignment')
    window.geometry('500x600')
    order_label=tk.Label(window,text='order',font=(14))
    order_label.pack()
    order_msgbx=tk.Entry(window,show=None)
    print(type(order))
    order_msgbx.pack()
    R_s_label=tk.Label(window,text='Rs',font=(14))
    R_s_label.pack()
    R_s_msgbx=tk.Entry(window,show=None)
    R_s=R_s_msgbx.get()
    R_s_msgbx.pack()
    R_msgbx=[]
    C_msgbx=[]
    R_label_list=locals()
    C_label_list=locals()

    def RC_button():
        order=int(order_msgbx.get())
        print(order)
        window=tk.Tk()
        if order>0:
            for n in range(order):
                R_label_list['R_label_' + str(n+1)] = tk.Label(window,text='R'+str(n+1),font=(14))
                R_label_list['R_label_' + str(n+1)].pack()
                R_msgbx0=tk.Entry(window,show=None)
                R_msgbx.append(R_msgbx0)
                R_msgbx[n].pack()
                R.append(R_msgbx[n].get)
                C_label_list['C_label_' + str(n+1)] = tk.Label(window,text='C'+str(n+1),font=(14))
                C_label_list['C_label_' + str(n+1)].pack()
                C_msgbx0=tk.Entry(window,show=None)
                C_msgbx.append(C_msgbx0)
                C_msgbx[n].pack()
                C.append(C_msgbx[n].get)
    RC_button=tk.Button(window, text='OK',width=15,height=2,command=RC_button)
    RC_button.pack()
    window.mainloop()
GUI()

Quote:RC_button=tk.Button(window, text='OK',width=15,height=2,command=RC_button)
this statement calls itself when button pressed.

you need to do some renaming.

calling the function which is named same as button is bad coding, it will recreate widgets each time
and weird things will start at some point.

I strongly suggest taking a good tutorial (at least the parts about buttons)
I'd suggest: https://www.python-course.eu/python_tkinter.php
