SNAKE GAME IN PYTHON

 In this blog, I will provide you with the code of how to make simple snake game in     PYTHON.

NOTE:- Before giving you all the code I would like to tell that there are some files in the code that I  have  created of my own and then running it like the file of high scores, and the background music.

If you get an error, then don't panic just create the file of same name in your system or simply comment out that lines of code.

Before running this code please install PYGAME AND PANDAS in your systems.

 If you all need the explaination of the code, then please do comment and please also do tell whether do you all want more such minor projects or not.

If Yes, then in next blog I will share the code of how to make Voice recognition python program in your system.
