UJ Snake Using Python

Lets Dive Into The Code Directly:-

1. Draw the screen area.
2. Draw Snake And Food
3. Give your favourite to all
4. As you can see pygame lib is used for creating the design
5. Random lib is for generating the area where the food would appear.
6. If the snake touches the screen borders game ends there.
7. If the snake touches himself game ends there.
8. The Snake size would increase as he touches the food and the score gets updated by 1.
9. The food disappears and appears in different location when snake touches the food.
10. All Set!!!Play Now.
11. Still doubtful you can get it from here:-https://github.com/joshiupendra1995/PythonWorld/blob/master/SnakeGame.py
