How to make a tkinter button sit below other buttons?

Question

I am currently in the middle of coding a small app which involves a menu written in tkinter (python 3.11) I have two option buttons, and I want to add an exit button under them. Currently it looks something like this:


import tkinter as tk
root = tk.Tk()
root.title("Window title")
root.config(bg='#FFFFFF')
frame = tk.Frame(
    master=root,
    bg='#FFFFFF'
)
frame.pack(side=tk.TOP, fill=tk.BOTH, expand=True)

label = tk.Label(
    master=frame,
    text="Select an option",
    height=1,
    width=40,
    bg='#FFFFFF'
)
label.pack(side=tk.TOP, fill=tk.BOTH, pady=4)

btn1 = tk.Button(
    master=frame,
    text="Option 1",
    height=1,
    width=20,
    bg='#FFFFFF'
)
btn1.pack(side=tk.LEFT, fill=tk.BOTH, padx=4, pady=4)

btn2 = tk.Button(
    master=frame,
    text="Option 2",
    height=1,
    width=20,
    bg='#FFFFFF'
)
btn2.pack(side=tk.RIGHT, fill=tk.BOTH, padx=4, pady=4)

exit_btn = tk.Button(
    master=frame,
    text="Exit",
    height=1,
    width=5,
    bg='#FFFFFF'
)
exit_btn.pack(side=tk.BOTTOM, fill=tk.BOTH, padx=4, pady=4)

root.mainloop()

I have tried passing side=tk.BOTTOM when packing the button but that doesn't seem to help and the exit button is still in the middle instead of below the others

You can create another frame called "bottom" to help organize your buttons:


import tkinter as tk
root = tk.Tk()
root.title("Window title")
root.config(bg='#FFFFFF')
frame = tk.Frame(
    master=root,
    bg='#FFFFFF'
)
frame.pack(side=tk.TOP, fill=tk.BOTH, expand=True)

bottom = tk.Frame(
    master=root,
    bg='#FFFFFF'
)
bottom.pack(side=tk.BOTTOM, fill=tk.BOTH, expand=True)


label = tk.Label(
    master=frame,
    text="Select an option",
    height=1,
    width=40,
    bg='#FFFFFF'
)
label.pack(side=tk.TOP, fill=tk.BOTH, pady=4)

btn1 = tk.Button(
    master=frame,
    text="Option 1",
    height=1,
    width=20,
    bg='#FFFFFF'
)
btn1.pack(side=tk.LEFT, fill=tk.BOTH, padx=4, pady=4)

btn2 = tk.Button(
    master=frame,
    text="Option 2",
    height=1,
    width=20,
    bg='#FFFFFF'
)
btn2.pack(side=tk.RIGHT, fill=tk.BOTH, padx=4, pady=4)

exit_btn = tk.Button(
    master=bottom,
    text="Exit",
    height=1,
    width=5,
    bg='#FFFFFF'
)
exit_btn.pack(fill=tk.BOTH, padx=4, pady=4)

root.mainloop()

Result is here

The order of packing the widgets matters. You need to pack label and exit_btn first, so they occupy the top and bottom sides. Then pack btn1 and btn2.

import tkinter as tk

root = tk.Tk()
root.title("Window title")
root.config(bg='#FFFFFF')

frame = tk.Frame(
    master=root,
    bg='#FFFFFF'
)
frame.pack(side=tk.TOP, fill=tk.BOTH, expand=True)

label = tk.Label(
    master=frame,
    text="Select an option",
    height=1,
    width=40,
    bg='#FFFFFF'
)

btn1 = tk.Button(
    master=frame,
    text="Option 1",
    height=1,
    width=20,
    bg='#FFFFFF'
)

btn2 = tk.Button(
    master=frame,
    text="Option 2",
    height=1,
    width=20,
    bg='#FFFFFF'
)

exit_btn = tk.Button(
    master=frame,
    text="Exit",
    height=1,
    width=5,
    bg='#FFFFFF'
)

label.pack(side=tk.TOP, fill=tk.BOTH, pady=4)
exit_btn.pack(side=tk.BOTTOM, fill=tk.BOTH, padx=4, pady=4)

btn1.pack(side=tk.LEFT, fill=tk.BOTH, padx=4, pady=4)
btn2.pack(side=tk.RIGHT, fill=tk.BOTH, padx=4, pady=4)

root.mainloop()

Result
