Python: Spirograph
Learning : Python
Subject: Writing Python codes to generate Spirograph Art
Writing codes to draw always funny time for me, playing around numbers, changing attributes to get something new and changing it again .. and again ..
In this post, we will write a code to draw some spirograph shapes, easy and shrort code will do the job. So lets Start ..
We will use Python Library turtle to draw, and will write one Function call it def draw_it(h,sz,ang) will take three arguments: h:number of heads, sz: size, ang: angle, then we will call this function to draw our Spirograph Art.
Code:
First we will set-up the turtle:
# turtle set-up
import turtle
t = turtle.Turtle()
t.shape("dot")
t.speed(0)
t.hideturtle()
Then here is the main Function to draw our graphs
# draw_it() function
def draw_it(h,sz,ang) :
c = 0
while True :
for i in range (h) :
t.forward(sz)
t.right(360/h)
t.right(ang)
c +=1
if c >=360/ang :
break
Then we call the function and pass the parameters, I tried several combinations and will include them in the source file in Download section. Here are some out-puts.
| Calling: t.pencolor(‘lightgray’) draw_it(19,19,19) t.pencolor(‘gray’) draw_it(17,17,17) t.pencolor(‘black’) draw_it(15,15,15)

Hope you enjoy, have fun and change the numbers to get new shapes ..

Here is another attempt to improve my skills in sketching and Coloring using water color. Mushroom House.
Another SketcheBook
After my 6th Sketchebooks I start creating sketchebooks for my self, cutting the A4 papers, punch or glue them together then creating the cover and Sketch over it, other sketchbooks are purchased online then again I draw/sketch on it’s cover. Sample of what I made here ..
Sketch Books 12, 13 Here
Sketch Books 22, 23 Here
This one here is my 42nd Sketchebook Cover, I purchased this from AliExpress site, verey nice and small but the papers are very thin and the colors appear on the other side of the page, over all, they are doing the job.

Sketch to Relax
This is a last night Sketch, just to break or stop thinking in codes and functions that are not working well. I think I need to stop codeing for 2-3 Days.
Taking pictures is not my main daily practices, but when i start playing with my camera, i really enjoy my self.
Thanks for visiting my Space..
