# Python – Draw Octagonal shape Using Turtle Graphics

In this article we will learn how to Make an Octagon using Turtle Graphics in Python. For that lets first know what is Turtle Graphics.

### Turtle graphics

• backward(length): moves the pen in the backward direction by x unit.
• right(angle): rotate the pen in the clockwise direction by an angle x.
• left(angle): rotate the pen in the anticlockwise direction by an angle x.
• penup(): stop drawing of the turtle pen.
• pendown(): start drawing of the turtle pen.

## Approach

• import the turtle modules.
• Get a screen to draw on
• Define an instance for turtle.
• For a drawing an Octagon execute a loop 8 times.
• In every iteration move turtle 100 units forward and move it left 45 degrees( corresponding to 135 degrees between two sides, so 180-135=45 degrees).
• This will make up an angle 135 degree between 2 sides.
• 8 iterations will make up an Octagon perfectly.

Below is the Python implementation of the above approach:

## Python3

 `# import for turtle module ` `import` `turtle ` ` `  `# making a workScreen ` `ws ``=` `turtle.Screen() ` ` `  `# defining a turtle instance ` `geekyTurtle ``=` `turtle.Turtle() ` ` `  `# iterating the loop 8 times ` `for` `i ``in` `range``(``8``): ` `  ``# moving turtle 100 units forward ` `  ``geekyTurtle.forward(``100``) ` `  ``# turning turtle 45 degrees so as to make perfect angle for an octagon ` `  ``geekyTurtle.left(``45``)`
