蟒蛇：Triacontagon轮

Question

因此，我知道如何制作三棱锥，但是我试图弄清楚如何使其几乎像一个轮子一样（如何基本上制造辐条）。如果可以的话，那就太好了！

import turtle
turtle.hideturtle()

turtle.up()
turtle.goto(0,150)
turtle.down()

numberOfSides = 30
lengthOfSide = 50
exteriorAngle = 360/numberOfSides
for i in range(numberOfSides):
    turtle.forward(lengthOfSide)
    turtle.right(exteriorAngle)

我希望它看起来像什么：

Answer 1

尝试以下代码：

import turtle
import math
num=30
A=turtle.position()
side=50
x=(side/2)/math.sin(math.radians(180/num))

#x contains the length of one spoke of wheel
ext=90+(180/num)
turtle.setheading(0)
for i in range(num):
    turtle.forward(x)
    turtle.left(ext)
    turtle.forward(side)
    turtle.left(ext)
    turtle.forward(x)
    turtle.setheading((i+1)*(360/num))
 # the loop makes one triangle of polygon

Answer 2

这是我的解决方法：

from turtle import *
circle(100)
left(90)
speed(10000000)
fd(100)
for i in range(60):
    fd(100)
    back(100)
    left(12)

这会吸引31条辐条，所以算出30条辐条，使我成为59。

Answer 3

尝试以最少的附加代码从您所要到达的地方：

import turtle

numberOfSides = 30
lengthOfSide = 75
exteriorAngle = 360 / numberOfSides

turtle.hideturtle()
turtle.sety(-lengthOfSide)

for i in range(numberOfSides):
    turtle.circle(lengthOfSide, extent=exteriorAngle, steps=1)
    position = turtle.position()
    turtle.goto(0, 0)
    turtle.setposition(position)

turtle.done()
