以下是一个使用 Python 和 PyGame库在 PyCharm中创建一个简单的小游戏（贪吃蛇游戏）的示例代码，希望对您有所帮助：

import pygame
import random# 基础设置
# 屏幕高度
SCREEN_HEIGHT = 480
# 屏幕宽度
SCREEN_WIDTH = 600
# 小方格大小
GRID_SIZE = 20# 颜色设置
WHITE = (255, 255, 255)
BLACK = (0, 0, 0)
GREEN = (0, 255, 0)# 初始化 `PyGame`
pygame.init()# 创建屏幕
screen = pygame.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT))
pygame.display.set_caption("贪吃蛇游戏")# 游戏时钟
clock = pygame.time.Clock()# 蛇的初始位置和速度
snake_pos = [200, 100]
snake_speed = [0, 0]# 食物的初始位置
food_pos = [random.randint(0, SCREEN_WIDTH // GRID_SIZE - 1) * GRID_SIZE,random.randint(0, SCREEN_HEIGHT // GRID_SIZE - 1) * GRID_SIZE]# 蛇的身体列表
snake_body = [[snake_pos[0], snake_pos[1]]]# 游戏结束标志
game_over = False# 游戏循环
while not game_over:for event in pygame.event.get():if event.type == pygame.QUIT:game_over = Trueif event.type == pygame.KEYDOWN:if event.key == pygame.K_UP and snake_speed[1]!= GRID_SIZE:snake_speed = [0, -GRID_SIZE]elif event.key == pygame.K_DOWN and snake_speed[1]!= -GRID_SIZE:snake_speed = [0, GRID_SIZE]elif event.key == pygame.K_LEFT and snake_speed[0]!= GRID_SIZE:snake_speed = [-GRID_SIZE, 0]elif event.key == pygame.K_RIGHT and snake_speed[0]!= -GRID_SIZE:snake_speed = [GRID_SIZE, 0]# 根据速度移动蛇头snake_pos[0] += snake_speed[0]snake_pos[1] += snake_speed[1]# 判断蛇是否吃到食物if snake_pos[0] == food_pos[0] and snake_pos[1] == food_pos[1]:food_pos = [random.randint(0, SCREEN_WIDTH // GRID_SIZE - 1) * GRID_SIZE,random.randint(0, SCREEN_HEIGHT // GRID_SIZE - 1) * GRID_SIZE]else:# 去除蛇尾del snake_body[0]# 判断蛇是否撞到自己或边界if [snake_pos[0], snake_pos[1]] in snake_body[1:]:game_over = Trueelif snake_pos[0] < 0 or snake_pos[0] >= SCREEN_WIDTH or snake_pos[1] < 0 or snake_pos[1] >= SCREEN_HEIGHT:game_over = True# 增加蛇的长度snake_body.append(list(snake_pos))# 绘制背景screen.fill(BLACK)# 绘制食物pygame.draw.rect(screen, GREEN, [food_pos[0], food_pos[1], GRID_SIZE, GRID_SIZE])# 绘制蛇for pos in snake_body:pygame.draw.rect(screen, WHITE, [pos[0], pos[1], GRID_SIZE, GRID_SIZE])# 刷新屏幕pygame.display.flip()# 控制游戏帧率clock.tick(10)# 退出游戏
pygame.quit()

您可以在 PyCharm中运行这段代码，开始您的贪吃蛇游戏。当然，这只是一个简单的示例，您可以根据自己的需求对游戏进行扩展和完善。希望这个示例对您有帮助！如果您还有其他问题，欢迎继续提问
