Draw Concentric Circles with VIBGYOR Using Turtle in Python (original) (raw)

Last Updated : 15 Jul, 2025

Prerequisite: Turtle Programming Basics

Turtle is an inbuilt module in Python. It provides drawing using a screen (cardboard) and turtle (pen). To draw something on the screen, we need to move the turtle (pen). To move turtle, there are some functions i.e forward(), backward(), etc.

To draw Concentric VIBGYOR :

Following steps are used :

• Importing turtle module
• Set a screen
• Make Turtle object
• Define a method for circle with dynamic radius and colour.
• Write text by setting turtle object at required position.

Below is the implementation :

Python3 `

import turtle package

import turtle

Screen object

sc = turtle.Screen()

Screen background color

sc.bgcolor('black')

turtle object

pen = turtle.Turtle()

turtle width

pen.width(4)

function to draw a circle of

rad radius and col color

def circle(col, rad, val):

pen.color(col)
pen.circle(rad)
pen.up()

# set position for space
pen.setpos(0, val)
pen.down()

function to write text

by setting positions

def text():

pen.color('white')
pen.up()
pen.setpos(-100, 140)
pen.down()
pen.write("Concentric VIBGYOR", 
          font = ("Verdana", 15))
pen.up()
pen.setpos(-82, -188)
pen.down()
pen.write("Using Turtle Graphics", 
          font = ("Verdana", 12))
pen.hideturtle()

Driver code

if name == "main" :

VIBGYOR color list

col = ['violet', 'indigo', 'blue',
     'green', 'yellow', 'orange',
     'red']

7 Concentric circles

for i in range(7):

  # function call
  circle(col[i], -20*(i+1), 20*(i+1))

function call

text()

`

Output :

Concentric Vibgyor
