Python Turtle Tutorial

1. Turtle code to draw Apple logo.

from turtle import *
width(10)
begin_fill()
left(160)
circle(100, 100)
circle(200, 60)
circle(40, 90)
circle(-40, 100)
circle(40, 100)
circle(200, 30)
left(90)
circle(-70, 150)
left(120)
circle(160, 55)
end_fill()
right(110)
up()
forward(25)
down()
begin_fill()
circle(-110, 90)
right(90)
circle(-110, 90)
end_fill()
done()

2. Prog to Make a small & colourfull design.

from turtle import *
import colorsys
speed(0)
bgcolor("black")
h = 0
for i in range(16):
    for j in range(18):
        c = colorsys.hsv_to_rgb(h, 1, 1)
        color(c)
        h += 0.005
        rt(90)
        circle(150 - j * 6, 90)
        lt(90)
        circle(150 - j * 6, 90)
        rt(180)
    circle(40, 24)
done()

3. Big Rangoli

from turtle import *
import colorsys

bgcolor ('black')
tracer (500)

def draw():
    h = 0
    for i in range(100):
        c = colorsys.hsv_to_rgb(h,1,1)
        h += 0.5
        up()
        goto(0,0)
        down()
        color('white')
        fillcolor(c)
        begin_fill()
        rt(98)
        circle(i,12)
        fd(i)
        lt(29)
        for j in range(129):
            fd(i)
            circle(j,299,steps=2)
        end_fill()

draw()
done()
