pycharm贪吃蛇代码

PyCharm 是一款Python集成开发环境，可以用于编写和调试Python程序。关于贪吃蛇代码，它是一个比较经典的小游戏，可以通过Python语言编写实现。以下是一个简单的贪吃蛇代码示例：

import pygame, sys, random, time
from pygame.locals import *

# 初始化pygame库
pygame.init()

# 设置窗口大小
WINDOW_WIDTH = 640
WINDOW_HEIGHT = 480
CELL_SIZE = 20

# 设置颜色
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
RED = (255, 0, 0)

# 创建一个窗口
window_surface = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))
pygame.display.set_caption('Greedy Snake')

# 定义一个函数，用来画蛇和食物
def draw_item(item_x, item_y, item_color):
    pygame.draw.rect(window_surface, item_color, Rect(item_x, item_y, CELL_SIZE, CELL_SIZE))

# 定义一个函数，用来打印文字
def print_text(font, x, y, text, color):
    imgText = font.render(text, True, color)
    window_surface.blit(imgText, (x, y))

# 设置字体
font1 = pygame.font.SysFont('SimHei', 24)
font2 = pygame.font.Font(None, 72)

# 定义游戏状态常量
GAME_OVER = -1
GAME_RUN = 0
GAME_WIN = 1

# 定义蛇的初始位置和长度
snake_position = [(0, 0), (20, 0), (40, 0), (60, 0)]
snake_length = 4
snake_direction = 'right'

# 定义食物的初始位置
food_position = (100, 100)

# 定义游戏状态

# 设置游戏帧率
fps_clock = pygame.time.Clock()

    # 处理游戏事件
