1、按钮对话框，并显示输入对应的内容

from tkinter import *
    import tkinter.messagebox as messagebox
    
    class Application(Frame):
        def __init__(self, master=None):
            Frame.__init__(self, master)
            self.pack()
            self.createWidgets()
    
        def createWidgets(self):
            self.nameInput = Entry(self)
            self.nameInput.pack()
            self.alertButton = Button(self, text='Hello', command=self.hello)
            self.alertButton.pack()
    
        def hello(self):
            name = self.nameInput.get() or 'world'
            messagebox.showinfo('Message', 'CT/TE, %s' % name)
    
    app = Application()
    # 设置窗口标题:
    app.master.title('独爱空城梦')
    # 主消息循环:
    app.mainloop()

2、文本框，显示相对应的文字

import tkinter as tk
    
    app = tk.Tk()
    app.title("FishC Demo")
    #标签控件；可以显示文本和位图
    theLable = tk.Label(app, text="你若安好，便是晴天",width=20,height=10)
    theLable.pack()
    
    app.mainloop()

3、按钮与文本框，运行该代码时，点击按钮，在控制台会输出相对应的文字

import tkinter as tk
    class App: #定义类
        
        def __init__(self, master):
            frame = tk.Frame(master)#定义窗体框架
            frame.pack(side=tk.RIGHT, padx=100,pady=100)
            
            #定义按钮
            self.hi_there = tk.Button(frame, text="打招呼",bg="red" ,fg='green',command=self.say_hi)
            self.hi_there.pack(padx=10, pady=10)#位置
            
        def say_hi(self):
            print("嗨，好久不见，你可安好！")
                 
    root = tk.Tk()
    app = App(root)
    root.mainloop()

4、制作一个动态的五颜六色的树

from turtle import *
    # 设置色彩模式是RGB:
    colormode(255)
    lt(90)
    lv = 14
    l = 120
    s = 45
    width(lv)
    # 初始化RGB颜色:
    r = 0
    g = 0
    b = 0
    pencolor(r, g, b)
    
    penup()
    bk(l)
    pendown()
    fd(l)
    
    def draw_tree(l, level):
        global r, g, b
        # save the current pen width
        w = width()
    
        # narrow the pen width
        width(w * 3.0 / 4.0)
        # set color:
        r = r + 1
        g = g + 2
        b = b + 3
        pencolor(r % 200, g % 200, b % 200)
    
        l = 3.0 / 4.0 * l
    
        lt(s)
        fd(l)
    
        if level < lv:
            draw_tree(l, level + 1)
        bk(l)
        rt(2 * s)
        fd(l)
    
        if level < lv:
            draw_tree(l, level + 1)
        bk(l)
        lt(s)
        width(w)
        
    speed("fastest")
    draw_tree(l, 4)
    done()
