Snake game with PyGame. Python

Snake game with PyGame

1.make sure that you have already installed pygame. or you have not installed yet ,don't worry let's install pygame by pip command:

pip install pygame

2.Let's paste this code on your favorite code editor and run this code.code is given below.

import pygame

import sys

import random

import time

pygame.init()

class Snake():

if dir=="RIGHT" and not self.direction=="LEFT":

self.direction = "RIGHT"

elif dir=="LEFT" and not self.direction=="RIGHT":

self.direction = "LEFT"

elif dir=="UP" and not self.direction=="DOWN":

self.direction = "UP"

elif dir=="DOWN" and not self.direction=="UP":

self.direction = "DOWN"

if self.direction == "RIGHT":

self.position[0] = self.position[0] + 10

elif self.direction == "LEFT":

self.position[0] = self.position[0] - 10

elif self.direction == "UP":

self.position[1] = self.position[1] - 10

elif self.direction == "DOWN":

self.position[1] = self.position[1] + 10

self.body.insert(0,list(self.position))

if self.position == foodPos:

return 1

else:

return 0
