turtle.fillcolor(colorstring) 绘制图形的填充颜色

turtle.begin_fill() 准备开始填充图形

turtle.end_fill() 填充完成

turtle.hideturtle() 隐藏画笔的turtle形状

turtle.showturtle() 显示画笔的turtle形状

urtle.pendown() 移动时绘制图形，缺省时也为绘制

turtle.goto(x,y) 将画笔移动到坐标为x,y的位置

turtle.penup() 提起笔移动，不绘制图形，用于另起一个地方绘制

turtle.circle() 画圆，半径为正(负)，表示圆心在画笔的左边(右边)画圆
