Python是一種功能強大的編程語言，廣泛用于開發各種應用程序和游戲。在此，我們將介紹如何使用Python編寫一個簡單的街機小游戲。

#導入必要的庫
import pygame
import random
#初始化Pygame游戲引擎
pygame.init()
#定義游戲窗口
win_width = 600
win_height = 400
win = pygame.display.set_mode((win_width, win_height))
#定義游戲元素
player_width = 60
player_height = 80
player_x = win_width // 2 - player_width // 2
player_y = win_height - player_height
player_speed = 5
player_image = pygame.image.load("player.png")
enemy_width = 50
enemy_height = 50
enemy_x = random.randrange(0, win_width - enemy_width)
enemy_y = -enemy_height
enemy_speed = 1
enemy_image = pygame.image.load("enemy.png")
score = 0
score_font = pygame.font.Font(None, 36)
#游戲主循環
running = True
while running:
#事件處理
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
#移動玩家
keys = pygame.key.get_pressed()
if keys[pygame.K_LEFT] and player_x >0:
player_x -= player_speed
if keys[pygame.K_RIGHT] and player_x< win_width - player_width:
player_x += player_speed
#移動敵人
enemy_y += enemy_speed
if enemy_y >win_height:
enemy_x = random.randrange(0, win_width - enemy_width)
enemy_y = -enemy_height
score += 1
#繪制游戲元素
win.fill((255, 255, 255))
win.blit(player_image, (player_x, player_y))
win.blit(enemy_image, (enemy_x, enemy_y))
score_text = score_font.render("Score: " + str(score), True, (0, 0, 0))
win.blit(score_text, (10, 10))
pygame.display.update()
#退出Pygame游戲引擎
pygame.quit()

這個游戲使用了Pygame庫來創建游戲窗口、加載圖像、處理事件和更新游戲狀態。游戲的主循環周期性地處理事件、更新游戲元素、繪制游戲場景和更新分數。
