We are providing you the code for a full working Snake Game in Python using Pygame. Most of us may have played this interesting game in our childhood.
For this game to run in your system you should have pygame installed in your system.
To install pygame in your system, type the following commands in your terminal–
"pip install pygame"
If this does not work then try this one–
"py -m pip install -U pygame --user"
Some short–
"py -m pip install pygame"
Lets see the code now.
