tkinter python not changing the location of buttons

from tkinter import *
root = Tk()

root.title('Timer')
root.geometry('500x500')
button2 = Button( root, text=2, padx=40, pady=20)
button2.pack()
button2.place(bordermode=INSIDE, relx=0.4, rely=0.4)

root.mainloop()

You could experiment with the relative height and relative width, but it will change if you resize the window manually through mouse drag.

If you want the window to not get resized, then you can follow below code.

from tkinter import *
root = Tk()

root.title('Timer')
root.geometry('500x500')
root.resizable(width=False, height=False)
button2 = Button( root, text=2, padx=40, pady=20)
button2.pack()
button2.place(bordermode=INSIDE, relx=0.4, rely=0.4)

root.mainloop()

It looks like there’s a small syntax error in the code, and the button is not appearing at the center of the window because the row and column values for the grid method are not set correctly. Let’s correct the code:

from tkinter import *

root = Tk()
root.title('Timer')
root.geometry('500x500')

# Create a frame to contain the button
frame = Frame(root)
frame.pack(expand=True)

# Create the button and add it to the frame
button_2 = Button(frame, text="Start Timer", padx=40, pady=20)
button_2.pack(pady=50)  # Add padding to push the button down

root.mainloop()

In this revised code:

• We create a Frame widget to contain the button. This allows us to use the pack method to center the button vertically within the window.
• The button is added to the frame using the pack method with appropriate padding (pady) to center it vertically.

Now, when you run this code, the “Start Timer” button should appear in the center of the window both horizontally and vertically. Adjust the padding value as needed to achieve the desired appearance.
