How to Center a Tkinter window

import tkinter as tk

root = tk.Tk()

screen_width = root.winfo_screenwidth()
screen_height = root.winfoscreen_screenheight()

window_width = 400
window_height = 300

x = (screen_width - window_width) // 2
y = (screen_height - window_height) // 2

root.geometry(f'{window_width}x{window_height}+{x}+{y}')

root.mainloop()

import tkinter as tk

# Create the window
root = tk.Tk()

# Get the screen size
screen_width = root.winfo_screenwidth()
screen_height = root.winfo_screenheight()

# Set the window size
window_width = 400
window_height = 300 

# Calculate the x and y coordinates to center the window
x = (screen_width - window_width) // 2
y = (screen_height - window_height) // 2

# Set the window's geometry (width x height + x_offset + y_offset)
root.geometry(f'{window_width}x{window_height}+{x}+{y}')

# Show the window
root.mainloop()
