用java写一个程序_CMS教程

先下载安装好python程序。

在我们自己的电脑上找到python的IDLE工具。打开IDLE，新建一个文件，命名为test1py。我们就开始导入turtle库，然后编辑代码。importturtleimporttime

输入代码完成后，点击保存。选择工具栏中的“run”->“runmodule”，即可运行看到效果。

Python由荷兰数学和计算机科学研究学会的GuidovanRossum于1990年代初设计，作为一门叫做ABC语言的替代品。Python提供了高效的高级数据结构，还能简单有效地面向对象编程。Python语法和动态类型，以及解释型语言的本质，使它成为多数平台上写脚本和快速开发应用的编程语言，随着版本的不断更新和语言新功能的添加，逐渐被用于独立的、大型项目的开发。

Python解释器易于扩展，可以使用C或C++（或者其他可以通过C调用的语言）扩展新的功能和数据类型。Python也可用于可定制化软件中的扩展程序语言。Python丰富的标准库，提供了适用于各个主要系统平台的源码或机器码。

下面是我以前做的小程序，希望能给你点帮助！

}

public void actionPerformed(ActionEvent e) {

// TODO Auto-generated method stub

if(egetActionCommand()equals("打印预览")){

thisrepaint();

}

使用drawLine()做了一个记账凭证。

执行点击"打印"子菜单"打印预览"就可显示出我们所画的"记账凭证表"

希望这个小程序能够给你点灵感

楼主给你一个我编的，直接保存成pbjava编译运行，就是你要的画图功能
