python tkinter选项卡问题

Question

tkinter nootbook选项卡怎么竖向排列？查了好多文章都是横着排开的，我想做成竖着排列的，竖着有足够空间显示出所有分类，也更美观

import tkinter as tk
from tkinter import ttk

root = tk.Tk()

style = ttk.Style(root)
style.configure('lefttab.TNotebook', tabposition='ws')

notebook = ttk.Notebook(root, style='lefttab.TNotebook')
f1 = tk.Frame(notebook, bg='gray', width=200, height=200)
f2 = tk.Frame(notebook, bg='blue', width=200, height=200)
f3 = tk.Frame(notebook, bg='green', width=200, height=200)
notebook.add(f1, text='Frame 1')
notebook.add(f2, text='Frame 2')
notebook.add(f3, text='Frame 3')
notebook.pack()

root.mainloop()
