I am having a problem with, only having a single label to show in an instance of clicking the radio button. I want to show that label depending with the radio-button I clicked, I tried reading about pack/grid_forget, but I think I still don't understand it pretty well, or I am just doing it really wrong in my code.
from tkinter import *
root = Tk()
# I squeezed them inside a frame, just for aesthetic reasons.
btn_frame = LabelFrame(root, text='', padx=20, pady=20)
btn_frame.grid(row=0, column=0, columnspan=3, padx=10, pady=10)
# I use button widgets, instead of other widgets.Because I felt buttons are square, and they are easy
to visualize.
red_btn = Button(btn_frame, text='R', padx=40, pady=40)
blue_btn = Button(btn_frame, text='B', padx=40, pady=40)
green_btn = Button(btn_frame, text='G', padx=40, pady=40)

So I am new in Python, I've just recently understood the 4/5 core fundamentals in every prog-language.
And now I am trying to learn about GUI with python, with Tkinter. I think my code got a bit longer, for something so simple and small. You can lecture my anyway you want, I just want learn good practices, and work on bad habits I may be doing.
I figured out that I should make my widgets global, and just make an update function to display every time an instance of them is created.
I want to thank Tim Roberts for helping me.

I am trying to build a calculator but I don't know how to make vertical space between buttons. I used pady for that but I didn't exactly understand how it works so I think it doesn't work for that don't worry about that 9 and 0 it is because of photo
You need to add the padx and pady args to the grid() calls, e.g.:
buton1.grid(row=1, column=0, padx=10, pady=10)
Setting the padding on the Button widgets just sets their internal padding (makes them wider / taller)
Bonus Round
def button_write(button):
print(button) # do whatever you need to do here
for i, n in enumerate(range(9, -1, -1)):
btn = tk.Button(root, text=n, command=lambda btn=n: button_write(btn))
y, x = divmod(i, 3)
btn.grid(row=y, column=x, padx=10, pady=10)
I want to remove the buttons "play" and "help" by pressing just on button "play". How can I do that? I need that the button "play" destroy himself and in addition destroy the button "help"
This is my code:
from tkinter import *
import tkinter.messagebox
from random import *
window = Tk()
window.title("Simon")
window.geometry("300x200")
label = Label(window, text="Simon Game!", font=("Ariel", 80),
bg="CadetBlue3")
label.pack()
window.configure(bg="CadetBlue3")
def destroy(button):
def inner():
button.destroy()
return inner
def click_help_button():
tkinter.messagebox.showinfo("Instructions", "The device
creates a series of tones and lights and requires a user to
repeat the sequence. If the user succeeds, the series becomes
progressively longer and more complex. Once the user fails, the
game is over")
help_btn = Button(window, width=12, height=2, text="Help",
bg="grey",font=("Ariel", 18), command=click_help_button)
help_btn.pack(side='bottom')
help_btn.place(x=800, y=150)
start_btn = Button(window, width=12, height=2, text="Play",
bg="grey", font=("Ariel", 18), command=destroy(help_btn))
start_btn.pack(pady=10)
start_btn.place(x=525, y=150)
start_btn.config(command=destroy(start_btn))
red_btn = Button(window, width=35, height=15, bg='red')
red_btn.place(x=495, y=270)
green_btn = Button(window, width=35, height=15, bg='green')
green_btn.place(x=750, y=270)
blue_btn = Button(window, width=35, height=15, bg='blue')
blue_btn.place(x=495, y=495)
yellow_btn = Button(window, width=35, height=15, bg='yellow')
yellow_btn.place(x=750, y=495)
window.mainloop()
Thanks to those who help!
I would make a click_play_button function
def click_play_button():
start_btn.destroy()
help_btn.destroy()
And call on it when pressing the play button
start_btn = Button(window, width=12, height=2, text="Play",
bg="grey", font=("Ariel", 18), command=click_play_button)
start_btn.pack(pady=10)
start_btn.place(x=525, y=150)
Below also worked...
def destroy(button):
button.destroy()
def click_help_button():
tkinter.messagebox.showinfo("Instructions", "The device")
help_btn = Button(window, width=12, height=2, text="Help",
bg="grey", font=("Ariel", 18), command=click_help_button)
help_btn.pack(side='bottom')
help_btn.place(x=800, y=150)
start_btn = Button(window, width=12, height=2, text="Play",

this is simple calculiator that do num + num = res : need to get num + num + num ...etc = rez is it posible corecct this code

is it posible to do only with def button_add(): function?

As it has already been noted, you are indeed using pack().
Try commenting out the offending line (or remove it completely) and setting input_num1 to occupy row 4, column 5 in the grid, like this:
input_num1 = Entry(root)
#input_num1.pack() <----------------
input_num1.grid(row=4, column=5) <----------------

I've been trying to fix this error for many hours.
P.S. I don't actually know which line the error is on, because it's saying that the error is on line 1705, even though the code is only 101 lines
In this line:
button_addition = Button(root, text="+", padx=40, pady=20, command=clickButton) # addition button
You are calling clickButton with no arguments, and in your function, you are requiring a number. You should use lambda, as you did with the other numbers (lines above), or call another function. By the look of your code, it should be button_add.
I fixed it this way:
myButtonSum = Button(root, text="+", padx=10, pady=5, command=lambda: buttonAdd("+"))
