Snake games:

Install pygame first. You can use pip to install pygame:

Pip install pygame

Run the following code:

#! /Usr/bin/env pythonimport pygame, sys, time, randomfrom pygame. locals import * # define the color variable redColour = pygame. color (255, 0, 0) blackColour = pygame. color (0, 0) whiteColour = pygame. color (255,255,255) greyColour = pygame. color (150,150,150) # define the gameOver function def gameOver (playSurface): gameOverFont = pygame. font. font ('arial. ttf', 72) gameOverSurf = gameOverFont. render ('game over', True, greyColour) gameOverRect = gameOverSurf. get_rect () gameOverRect. midtop = (320, 10) playSurface. BITs (gameOverSurf, gameOverRect) pygame. display. flip () time. sleep (5) pygame. quit () sys. exit () # define the main function def main (): # initialize pygame. init () fpsClock = pygame. time. clock () # create a pygame display layer playSurface = pygame. display. set_mode (640,480) pygame. display. set_caption ('Raspberry Snake ') # initialize the variable "Snail keposition" = [100,100] snail kesegments = [[100,100], [80,100], [60,100] raspberryPosition = [300,300] raspberrySpawned = 1 ction = 'right' changeDirection = direction while True: # detect pygame events such as buttons in pygame. event. get (): if event. type = QUIT: pygame. quit () sys. exit () elif event. type = KEYDOWN: # determine if event for a keyboard event. key = K_RIGHT or event. key = ord ('D'): changeDirection = 'right' if event. key = K_LEFT or event. key = ord ('A'): changeDirection = 'left' if event. key = K_UP or event. key = ord ('W'): changeDirection = 'up' if event. key = K_DOWN or event. key = ord ('s '): changeDirection = 'low' if event. key = K_ESCAPE: pygame. event. post (pygame. event. event (QUIT) # determine whether the inverse direction is input. if changeDirection = 'right' and not direction = 'left ': direction = changeDirection if changeDirection = 'left' and not direction = 'right': ction = changeDirection if changeDirection = 'up' and not direction = 'drop ': direction = changeDirection if changeDirection = 'low' and not direction = 'up': ction = changeDirection # if direction = 'right ': snail keposition [0] + = 20 if direction = 'left': snail keposition [0]-= 20 if direction = 'up ': snail keposition [1]-= 20 if direction = 'lowdown ': snail keposition [1] + = 20 # increase the length of the snake. insert (0, list (snkeposition) # determine whether Raspberry is eaten if the snakkeposition [0] = raspberryPosition [0] and snakkeposition [1] = raspberryPosition [1]: raspberrySpawned = 0 else: snkesegments. pop () # if you eat raspberry, regenerate raspberry if raspberrySpawned = 0: x = random. randrange (1, 32) y = random. randrange () raspberryPosition = [int (x * 20), int (y * 20)] raspberrySpawned = 1 # Draw the playSurface of the pygame display layer. fill (blackColour) for position in snail kesegments: pygame. draw. rect (playSurface, whiteColour, Rect (position [0], position [1], 20, 20) pygame. draw. rect (playSurface, redColour, Rect (raspberryPosition [0], raspberryPosition [1], 20, 20) # refresh the pygame display layer pygame. display. flip () # determine whether the result is dead if snail keposition [0]> 620 or snail keposition [0] <0: gameOver (playSurface) if snail keposition [1]> 460 or snail keposition [1] <0: for snail body in snail kesegments [1:]: if snail keposition [0] = snail kebody [0] and snail keposition [1] = snail kebody [1]: gameOver (playSurface) # control the speed of the game fpsClock. tick (5) if _ name _ = "_ main _": main ()

Operation Method:

Upper/lower left key or wsad Key Control

Exit the game with the ESC key
