图形用户界面和游戏开发
主要介绍下
tkinter和Pygame两个模块, 真搞gui有用专业点的，比如wxPython、PyQt、PyGTK之类的，学习pygame好好理解面向对象变成，真想搞游戏也是可以的，就得往细致了研究
wxpython 可以看这一篇https://www.cnblogs.com/morries123/p/8568666.html
1. 基于tkinter模块的GUI
GUI是图形用户界面的缩写，图形化的用户界面对使用过计算机的人来说应该都不陌生，在此也无需进行赘述。Python默认的GUI开发模块是tkinter（在Python 3以前的版本中名为Tkinter），从这个名字就可以看出它是基于Tk的，Tk是一个工具包，最初是为Tcl设计的，后来被移植到很多其他的脚本语言中，它提供了跨平台的GUI控件。
基本上使用tkinter来开发GUI应用需要以下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)。
大概看下，后面再专门搞个独立分支研究gui：
import tkinter
import tkinter.messagebox
def main():
flag = True
# 修改标签上的文字
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)
# 确认退出
def confirm_to_quit():
if tkinter.messagebox.askokcancel('温馨提示', '确定要退出吗?'):
top.quit()
# 创建顶层窗口
top = tkinter.Tk()
# 设置窗口大小
top.geometry('240x160')
# 设置窗口标题
top.title('小游戏')
# 创建标签对象并添加到顶层窗口
label = tkinter.Label(top, text='Hello, world!', font='Arial -32', fg='red')
label.pack(expand=1)
# 创建一个装按钮的容器
panel = tkinter.Frame(top)
# 创建按钮对象 指定添加到哪个容器中 通过command参数绑定事件回调函数
button1 = tkinter.Button(panel, text='修改', command=change_label_text)
button1.pack(side='left')
button2 = tkinter.Button(panel, text='退出', command=confirm_to_quit)
button2.pack(side='right')
panel.pack(side='bottom')
# 开启主事件循环
tkinter.mainloop()
if __name__ == '__main__':
main()
效果：

2.使用Pygame进行游戏开发
这段直接搬作者的了，主要学习思想
Pygame是一个开源的Python模块，专门用于多媒体应用（如电子游戏）的开发，其中包含对图像、声音、视频、事件、碰撞等的支持。Pygame建立在SDL的基础上，SDL是一套跨平台的多媒体开发库，用C语言实现，被广泛的应用于游戏、模拟器、播放器等的开发。而Pygame让游戏开发者不再被底层语言束缚，可以更多的关注游戏的功能和逻辑。

目前是点击之后可以出一个hero角色，然后又矩形吃了会变小，椭圆吃了会分裂，达到北京四分之一就结束了，回去重新搞一下，加点分裂之后还是跟着主体，然后让这东东智能点，变成策略游戏
