在 python 海龟中绘制印度国旗脉轮

Question

我正在使用乌龟和 python 绘制印度国旗。到目前为止，我已经得到了矩形和颜色，但我正在努力使脉轮位于中间。

它有24根辐条，周围是一个封闭的圆圈。有关如何完成此操作的任何提示？

现在这是我的代码：

import turtle

def drawRectangle (t, w, h, c):
    t.fillcolor(c)
    t.begin_fill()
    for i in range(2):
        t.forward(h)
        t.left(90)
        t.forward(w)
        t.left(90)
    t.end_fill()


def main ():
    wn = turtle.Screen()

    chloe = turtle.Turtle()
    drawRectangle(chloe,50,200, "chartreuse3")

    chloe.up()
    chloe.goto(0,-100)
    chloe.down()

    drawRectangle(chloe,50,200, "orange1")

    chloe.up()
    chloe.goto(100,-25)
    chloe.down()
    chloe.pencolor("blue4")

    for i in range(24):
        chloe.forward(20)
        chloe.backward(20)
        chloe.left(15)
    chloe.up()
    chloe.goto(300,300)

main()

Answer 1

您可以使用circle画圆：

chloe.pencolor("blue4")

# draw the spokes
for i in range(24):
    chloe.forward(20)
    chloe.backward(20)
    chloe.left(15)

# raise pen
chloe.up()

# head down
chloe.setheading(270)

# go forward 20
chloe.forward(20)

# reset heading
chloe.setheading(0)

# pen down
chloe.down()

# draw the circle
chloe.circle(20)

Answer 2

import turtle
def drawRectangle (t, l, b, c):
    t.fillcolor(c)
    t.begin_fill()
    for i in range(2):
        t.forward(b)
        t.left(90)
        t.forward(l)
        t.left(90)
    t.end_fill()


def main ():
   wn = turtle.Screen()

   india = turtle.Turtle()
   drawRectangle(india,50,200, "orange1")
   india.up()
   india.goto(0,-100)
   india.down()
   drawRectangle(india,50,200, "green")
   india.up()
   india.goto(100,-20)
   india.down()
   india.pencolor("blue3")

   for i in range(24):
    india.forward(20)
    india.backward(20)
    india.left(15)
    india.up()
    india.goto(400,400)

main()
