基于tkinter模块的GUI
使用tkinter开发GUI需要5个步骤：
导入tkinter模块中我们需要的东西创建一个顶层窗口对象并用它来承载整个GUI应用在顶层窗口对象上添加GUI组件通过代码将这些GUI组件的功能组织起来进入主事件循环(main loop)
实例
import tkinter
import tkinter.messagebox
def main():
flag = True
def change_label_text():
nonlocal flag
flag = not flag
color, msg = ('red', 'Hello world!')\
if flag else ('blue', 'Goodbye, world!')
label.config(text=msg, fg=color)
def confirm_to_quit():
if tkinter.messagebox.askokcancel('温馨提示', '确定要退出吗'):
top.quit()
top = tkinter.Tk()
top.geometry('240x160')
top.title('小游戏')
label = tkinter.Label(top, text='Hello,world',
font = 'Arial -32', fg = 'red')
label.pack(expand = 1)
panel = tkinter.Frame(top)
button1 = tkinter.Button(panel, text='修改', command = change_label_text)
button2 = tkinter.Button(panel, text='退出', command = confirm_to_quit)
button1.pack(side='left')
button2.pack(side='right')
panel.pack(side='bottom')
