# Python – Draw Octagonal shape Using Turtle Graphics

• Last Updated : 19 Oct, 2020

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 the turtle.
• For a drawing, an Octagon executes a loop 8 times.
• In every iteration move the 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 of 135 degrees 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``)`

Output: Octagon
