Learn How To Create A Python Snake Game Using Python IDE

Python Snake Game


In this blog, you will learn how to create the very famous arcade game, Snake using Python. The player will be responsible to help the snake find food, grow and most importantly avoid colliding with barriers such as its own self.

Here are steps that you can need to follow to get started building your very own version of this classic game:

Step 1 – In order to get started, we will first import define random, turtle, and time, packages. Now, create class Square and declare the x and y variables. After this generate a self function to draw a black box coordinate. Use the for loop in range to add them, y coordinates. By using for loop initially range is 4.
create class Square
Step 2 – Now, we will create the Foodl class using the same x,y coordinates and keep the state as ON. Create the Food class and define changelocation(self), drawself(), changestate() function. The changelocation(self) function will allocate the food a random value of x,y coordinate. The food keeps itself away from the snake’s body by blinking on and off. We will control this using the drawself () and changestate () functions.
create the Food class
Step 3 – Create the Snake class which has the init() function that contains the variable next which tells the snake which way to go next. Further functions defined determine collision detection, moving the snake head to the next spot and even resets the head and next position.
Create Snake class
Step 4 – Now that we have already created the Food and the Snake, we will now create the game play and define the snake’s movements. We start by creating the Game class which will include the functions moveup(), movedown(), moveleft(), moveright() to change a location and snake position on a screen. These functions will help our snake move in the directions the user selects on the screen.
create Game class
Step 5 – This set of codes will allow the snake to extend itself by 1 after eating the food. By defining the movedown (), eatFood () and drawself () functions, you’ll be able to add to the tail and extend the snake by 1, as well as draw the whole snake when it is called.
Defining Movement
Step 6 – This section includes the conditions that allow the snake to move positions when the command is called. We will also include a print function in each for debugging purposes. This will display the snake on the screen.


OUTPUT – In order to run the game, go to the Python shell Editor and click on Run to Run Module F5. The snake game should start running and can move left down on a python turtle graphics.

Module F5

Step 2 – The snake can move Up/Down/Left /Right and eats the food to grow. Also, you can terminate the window which will show that the application has been destroyed.

Conclusion – In this article, we learned how to develop the popular snake game on the Python IDE. We also saw how to create the different Python functions like move up, down, left, right and to get the snake to eat food.


  1. HELP!! im having trouble getting the game running. I keep getting this come up and im not sure what to do
