Python-written Snake game example _python

This article mainly introduces Python to write the snake game example, practiced hand works, but also fun and can learn things, the need for friends can refer to the next

The first time in Python to write this more practical and fun things, the right to be practiced hand it

Game Description:

* P Key Control "pause/Start"
* Direction keys control the direction of the snake

The source code is as follows:
