tkinter中ttk.Notebook实现多页面切换

使用ttk.Notebook可实现实现多页面切换

直接上代码：

import tkinter as tk
from tkinter import ttk
from tkinter import END

class App:
    def __init__(self,master):
        self.notebook = ttk.Notebook(master)
        self.frame1 = tk.Frame(master)
        self.frame2 = tk.Frame(master)
        
        self.label = tk.Label(self.frame1, text='Python',font=('华文行楷',12))
        self.label.grid()
        self.entry1 = tk.Entry(self.frame1,width = 35)
        self.entry1.grid(row = 0,column=1)
        self.bu1 = tk.Button(self.frame1,text = '请点击1',command = self.bu1)
        self.bu1.grid(row=0,column=2)
        self.list1 = tk.Listbox(self.frame1,font=('微软雅黑',12),width=38,heigh=8)
        self.list1.grid(row=1,columnspan=5)
        
        
        self.bu2 = tk.Button(self.frame2, text='请点击2',command=self.bu2)
        self.bu2.grid()
        self.list2 = tk.Listbox(self.frame2,font=('微软雅黑',12),width=38,heigh=8)
        self.list2.grid(row=1,columnspan=5)
        self.notebook.add(self.frame1, text='test1')
        self.notebook.add(self.frame2, text='test2')
        self.notebook.pack(padx=10, pady=5, fill=tk.BOTH, expand=True)
        
        
    def bu1(self):
        self.list1.insert(END,self.entry1.get()+'人生苦短，我用Python')
        self.list1.see(END)
        self.list1.update()
        
        
    def bu2(self):
        self.list2.insert(END,'Python使我更加强大！')
        self.list2.see(END)
        self.list2.update()
