Python：Triacontagon Wh

Question

所以我知道怎么做一个曲安奈德，但我想弄清楚我怎么能使它几乎像一个轮子（如何使辐条本质上）。如果你能帮我太好了！你知道吗

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：

Answer 1

以下是我的解决方案：

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

这画了31根辐条，算出30根，只画59根。你知道吗

Answer 2

请尝试以下代码：

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 3

试图用最少的额外代码从您现在的位置到达您想要的位置：

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()
