1. 太阳花
   注意颜色的填充

import turtle as t
t.color("red","yellow")
t.speed(10)
t.begin_fill()
for _ in range(50):t.forward(200)t.left(170)
t.end_fill()
t.done()

2.五角星
注意画笔颜色和填充颜色的区别

import turtle
turtle.pensize(5)
turtle.pencolor("yellow")
turtle.fillcolor("red")
turtle.begin_fill()
for _ in range(5):turtle.forward(200)turtle.right(144)
d_fill()
turtle.done()

3.螺旋线
注意边长和i的关系

import turtle as t
t.speed("fastest")
t.pensize(3)
for i in range(100):t.fd(2*i)t.left(90)
t.done()

4.炫彩螺旋
注意颜色的轮流调用

import turtle
set()
turtle.pensize(2)
turtle.bgcolor("black")
colors=['red','yellow','purple','blue','green','grey']
for x in range(400):turtle.forward(2*lor(colors[x%6])turtle.left(29)
turtle.done()

注：
turtle.forward(2*x) 注意每条边的规律
