Draw a Tic Tac Toe Board using Python-Turtle

The Task Here is to Make a Tic Tac Toe board layout using Turtle Graphics in Python. For that lets first know what is Turtle Graphics.

Turtle graphics

In computer graphics, turtle graphics are vector graphics using a relative cursor upon a Cartesian plane. Turtle is drawing board like feature which let us to command a turtle and draw using it.

Features of 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.

import turtle

• Get a screen to draw on.

ws = turtle.Screen()

The screen will look like this.

• Define an instance for turtle.
• Here, i had manually set the speed of the turtle to 2.
• For a drawing a Tic Tac Toe board first we have to make an outer Square.
• Then we will Make inner lines of the square which will ultimately make up the board.
• For inner lines i had used penup(),goto() and pendown() method to take the pen up and then take it down at certain coordinates.
• The inner lines will make up the Tic Tac Toe board perfectly.
   

Below is the implementation of the above approach:

import turtle # getting a Screen to work on  ws=turtle.Screen() # Defining Turtle instance t=turtle.Turtle() # setting up turtle color to green  t.color("Green") # Setting Up width to 2 t.width("2") # Setting up speed to 2 t.speed(2) # Loop for making outside square of # length 300 for i in range(4): t.forward(300) t.left(90) # code for inner lines of the square t.penup() t.goto(0,100) t.pendown() t.forward(300) t.penup() t.goto(0,200) t.pendown() t.forward(300) t.penup() t.goto(100,0) t.pendown() t.left(90) t.forward(300) t.penup() t.goto(200,0) t.pendown() t.forward(300)
