如何在Tkinter的屏幕上居中显示窗口？

import tkinter as tk

screen_width = tk.Tk().winfo_screenwidth()
screen_height = tk.Tk().winfo_screenheight()

root = tk.Tk()
root.geometry("300x200")

win_width = root.winfo_reqwidth()
win_height = root.winfo_reqheight()

x_coordinate = int((screen_width / 2) - (win_width / 2))
y_coordinate = int((screen_height / 2) - (win_height / 2))

root.geometry(f"300x200+{x_coordinate}+{y_coordinate}")
