Draw Colorful Spiral Web Using Turtle Graphics in Python

Prerequisite: Turtle Basics

“Turtle” is a Python feature like a drawing board, which lets us command a turtle to draw all over it. This comes packed with the standard Python package and need not be installed externally.

Methods used:

• forward(value): moves the turtle in the forward direction.
• turtle.Pen(): setup the turtle pen
• speed(value): changes the speed of the turtle
• width(value): set the width
• left(value): moves the turtle left.
• bgcolor(color_name): changes background-color

Approach:

• Import turtle.
• Define colors using the list data structure in python.
• Setup a turtle pen for drawing the Spiral Web.
• Start making the Spiral Web according to your logic. 
  

Below is the implementation of the above approach.

Python3

# import turtle
import turtle

# defining colors
colors = ['red', 'yellow', 'green', 'purple', 'blue', 'orange']

# setup turtle pen
t= turtle.Pen()

# changes the speed of the turtle
t.speed(10)

# changes the background color
turtle.bgcolor("black")

# make spiral_web
for x in range(200):
    t.pencolor(colors[x%6]) # setting color
    t.width(x/100 + 1) # setting width
    t.forward(x) # moving forward
    t.left(59) # moving left

turtle.done()
t.speed(10)

turtle.bgcolor("black") # changes the background color

# make spiral_web
for x in range(200):
    t.pencolor(colors[x%6]) # setting color
    t.width(x/100 + 1) # setting width
    t.forward(x) # moving forward
    t.left(59) # moving left

turtle.done()

Output:
