第一周的python作业

1.五角星绘制

 

import turtle
turtle.fillcolor("red")
turtle.begin_fill()
while True:
    turtle.forward(220)
    turtle.right(144)
    if abs(turtle.pos()) < 1:
        break
turtle.fd(84)
for i in range(5):
    turtle.fd(52)
    turtle.right(72)
turtle.end_fill()
turtle.done()

2.六角形绘制

 

import turtle
turtle.pencolor("pink")
turtle.left(30)
turtle.forward(144)
turtle.right(60)
turtle.forward(144)
turtle.right(60)
turtle.forward(144)
turtle.right(60)
turtle.forward(144)
turtle.right(60)
turtle.forward(144)
turtle.right(60)
turtle.forward(144)
turtle.forward(144)
turtle.right(120)
turtle.forward(144)
turtle.left(60)
turtle.forward(144)
turtle.right(120)
turtle.forward(144)
turtle.left(60)
turtle.forward(144)
turtle.right(120)
turtle.forward(144)
turtle.left(60)
turtle.forward(144)
turtle.right(120)
turtle.forward(144)
turtle.left(60)
turtle.forward(144)
turtle.right(120)
turtle.forward(144)
turtle.left(60)
turtle.forward(144)
turtle.right(120)
turtle.forward(144)
turtle.exitonclick()

 

3.叠加等边三角形绘制

 

import turtle as t
t.pencolor("purple")  #笔触为紫色
#绘制外部大三角形
t.fd(200)
t.seth(120)
t.fd(200)
t.seth(-120)
t.fd(200)
#绘制内部小三角形
t.seth(0)
t.fd(100)
t.seth(60)
t.fd(100)
t.seth(180)
t.fd(100)
t.seth(-60)
t.fd(100)
t.seth(120)
t.fd(100)
t.seth(0)
t.done()
