turtle绘制多个五角星

学习了初步的使用turtle库，绘制简单的五角星

# coding=gbk
import turtle


# 画一个五角星
def star(size):
    for i in range(0, 5):
        turtle.fd(size)
        turtle.right(144)


# 指定初始长度，画多少个五角星，相邻五角星长度差
def some_star(init_size, count, step):
    for i in range(0, count):
        star(init_size+i*step)


# 递归的方法
def recursive(size, count, step):
    for i in range(0, 5):
        turtle.fd(size)
        turtle.right(144)
    size += step
    count -= 1
    if count > 0:
        recursive(size, count, step)


def main():
    # 一些方法的练习
    turtle.penup()
    turtle.forward(50)
    turtle.pendown()
    turtle.pensize(2)
    turtle.pencolor('red')

    # some_star(50, 5, 50)
    recursive(50, 5, 50)
    turtle.exitonclick()


if __name__ == '__main__':
    main()
