Python tkinter如何把窗口在屏幕中央居中

# -*- coding: utf-8 -*-
import tkinter as tk

# 创建 Tkinter 窗口
root = tk.Tk()
# 设置窗口大小
root.geometry("400x300")

# 获取屏幕宽度和高度
screenWidth = root.winfo_screenwidth()
screenHeight = root.winfo_screenheight()

# 计算窗口显示时的左上角坐标
centerX = int((screenWidth - root.winfo_reqwidth()) / 2)
centerY = int((screenHeight - root.winfo_reqheight()) / 2)

# 设置窗口显示时的左上角坐标
root.geometry("+{}+{}".format(centerX , centerY ))

# main function
if __name__ == '__main__':
	# 窗口主循环
	root.mainloop()
