import turtle

def main():
#pensize()  画笔大小
turtle.pensize(3)
#penup/down()   提起笔/放下
turtle.penup()
#goto()   画笔至（x,y）点
turtle.goto(-200,-50)
turtle.pendown()
#begin/end_fill()   开始/结束填充
turtle.begin_fill()
turtle.color("red")
#circle()   绘制图形，其中steps=n，n边形，若steps缺省则为圆
turtle.circle(40, steps=3)
turtle.end_fill()

turtle.penup()
turtle.goto(-100,-50)
turtle.pendown()
turtle.begin_fill()
turtle.color("blue")
turtle.circle(40, steps=4)
turtle.end_fill()

turtle.penup()
turtle.goto(0,-50)
turtle.pendown()

turtle.color("green")
turtle.circle(40, steps=5)
turtle.end_fill()

turtle.penup()

#font()   文本参数：字体，大小，样式
font = ("Times", 18, "bold"))
