Step by Step Procedure to create Snake game in Python
Hello friends how are you, Today in this post "Snake game in Python" i am going to teach you how you can create your own Snake Game in Python using very simple lines of code. Snake game is on of the most popular game which every programmer or learner wants to create so here you will get the complete code for snake game.
If you are a computer science students or teacher and want to learn something interesting in programming then just go through this post. This can also be a simple and interesting project for you.
In Snake Game there are two main elements in which one is Snake and the other is Fruit. When snake eats fruit then its tail grows longer, making the increasingly difficult. Some important rules for snake game is below.
- Snake moves at constant speed
- Snake can move only in direction NORTH, SOUTH, EAST AND WEST
- Direction of snake can be controlled using UP, DOWN, LEFT AND RIGHT keys
- Fruit appears at random location.
- When snake eats Fruit its tail gets longer.
- When snake crosses itself the game will over.
If you want to understand this through video then watch this video i have explained it step by step live
Now i am going to explain it step by step so just go through this post to understand this completely.
Step 1: Install Python : Click here to watch a video on how to install python or Open any browser and type Download Python and click the first link you will get official website of python here you will get a Download button and after clicking on this button you will get exe of latest python version just install it into your system.
Step 2: Install Pycharm | Create Project | Install Library: Click here to watch a single video on How to install Pycharm | Create Project | Install Library or To install Pycharm IDE Open any browser and type Download Pycharm and click the first link you will get official website of Pycharm here you will get a black download button and after clicking on this button you will get an exe of Pycharm , just install it into your system. If you are facing problem to install then watch the above video i have explained step by step.
Step 3: Create Project : Open Pycharm click on File which is in top left of screen and select New Project. Then you will get a screen. Here first you need to select directory of your project and then type a name for your project like "SnakeGame" after directory name, and at last click the create button to create this project.
Step 4: Create Python file: To create a python file for coding in your project just right click on project name "SnakeGame" and select new and click on Python File , you will get popup screen in which you have to type a name like "Program" for python file and press enter, it will create a python file with name Program.py inside the project SnakeGame.

Looking at your snake game in python, where would I find the two .pnl files - fruit and apple?
