python第一周：叠加等边三角形，红色五角星，六角形

一.使用turtle库绘制一个叠加等边三角形：

import turtle
turtle.right(60)
turtle.forward(200)
turtle.right(120)
turtle.forward(200)
turtle.right(120)
turtle.forward(200)
turtle.penup()
turtle.forward(-100)
turtle.pendown()
turtle.right(60)
turtle.forward(100)
turtle.right(120)
turtle.forward(100)
turtle.right(120)
turtle.forward(100)
turtle.done()

二.使用turtle库绘制一个红色五角星：

import turtle
turtle.fillcolor("red")
turtle.begin_fill()
turtle.pensize(2)
for i in range (5):
    turtle.forward(250)
    turtle.right(144)
turtle.end_fill()
turtle.done()

三.使用turtle库绘制一个六角形：

import turtle
turtle.pensize(3)
turtle.pu()
turtle.fd(-150)
turtle.pd()
turtle.left(30)
turtle.forward(300)
turtle.right(120)
turtle.forward(300)
turtle.left(60)
turtle.forward(-300)
turtle.penup()
turtle.left(60)
turtle.forward(100)
turtle.pendown()
turtle.left(60)
turtle.forward(100)
turtle.right(120)
turtle.forward(300)
turtle.right(120)
turtle.forward(300)
turtle.right(120)
turtle.forward(200)
turtle.done()
