如何用python语言表示一个三维的立方体，该怎么做

没有学过python，受邀回答就临时抱佛脚看看API学习了一下，给出作答代码，此代码依赖pythongraphics图形库（http://mcsp.wartburg.edu/zelle/python/graphics.py）：

#创建绘图窗口

#确定前面4个顶点坐标

#后面相对前面缩小并倾斜，产生透视效果

frontFace.draw(win);

backFace=Rectangle(p5,p7);

backFace.draw(win);

#补充前面到后面的4条边

line.draw(win);

line.draw(win);
