复习了去年暑假看的python课，大致过了一下，在输入上面，还是有些卡壳。
才知道py3把raw_input给去掉了。
好久没做题，格式化输出也忘记了，下面是我的智障敲打。

void setup(){
//初始化定义
size(500,500);//定义
background(214);//black:0 white:255
//ctrl+r:run
}

void draw(){
//background(255);
ellipse(250,250,100,100);//右键：在文档中搜索，有help
//processing的坐标轴体系：以左上角为(0,0)点
ellipse(mouseX,mouseY,100,100);
//有拖影是因为背景没有刷新，如果在draw里加上background(255)，就不会有拖影了~
}

void draw(){
background(255);
//以中心点rectMode(CENTER);
stroke(255,255,0);//对线条的颜色的改变
fill();//对对象填色
rect(width/2,height/2,400,400);
ellipse(width/2,height/2,100,100);//width和height分别表示画布的宽和高
point(width/2,height/2)
//ctrl+t:规整代码
}

void setup() {
  size(500, 500);//the size if
  background(214);//black:0 white:255
  //ctrl+r:run
}

void draw() {
  background(#B0DE00);
  rectMode(CENTER);
  stroke(#D13602);
  fill(#D13602);
  rect(width/2, height/2, 200, 200);
